The coherence of quantum computing is the essence of quantum parallel computing, but in reality, qubits will be affected by the external environment, resulting in quantum entanglement. Quantum coherence is highly susceptible to interference from quantum entanglement, resulting in a decrease in quantum coherence, also known as decoherence. In practical applications, it is impossible to avoid the contact between the qubits and the outside world, and the coherence of the quantum is not easy to maintain. Therefore, the quantum decoherence problem is one of the important problems that need to be solved at present, and its solution will affect the future development path of quantum computers to a certain extent.

After solving the quantum interference, there is also quantum entanglement.

Quantum, as the smallest particle, obeys the law of quantum entanglement. Even though quanta may be separated from each other spatially, interaction between quanta is unavoidable. In between, quantum entanglement technology is associated with the field of quantum information transmission. In a certain sense, the rapid speed of communication between quanta is used to realize the transfer of information.

And quantum parallel computing is also a difficult point. The unique parallel computing of quantum computers is an important point that classical computers cannot match. The same is an n-bit memory, and there is only one result for a classic computer to store. But quantum computers store results up to 2n. Its parallel computing not only far surpasses the latter in terms of storage capacity, but also has fast read speeds, allowing multiple reads and computations to be performed simultaneously. It is precisely the importance of quantum parallel computing that its effective application has become one of the keys to the development of quantum computers.

Of course, the most difficult part, and the gap that now exists before all technologies, is quantum unclonability. Quantum unclonability refers to the process by which there is no replication of any unknown quantum state, and since the quantum state is to be kept unchanged, there is no quantum measurement, and replication cannot be realized. For quantum computers, the error correction applications and replication capabilities of classical computers cannot be implemented – that is, unless a computer is designed that is 100% error-proof, this theory cannot be realized.

And it's impossible to make a mistake 100 percent.

The development of quantum computers is still based on contradictory theories, so General Kelsen said that quantum computers are a fallacy, and until this fallacy is solved, it is impossible for quantum computers to be put into use, let alone miniaturization, and he cracked the secret of that memory in two or three minutes with it in his hand......

But the facts are in front of him, and he can't help but believe it.

The storage data in that chip has already shown that all those sensitive coordinates are also places that satellites have explored, don't say that the space center has nothing to do with the Huaqi military, everyone knows that the space agency and the Citigroup military basically wear a pair of pants. NASA's state-of-the-art jet experiment propulsion is funded by the Citigroup military, and many of the projects developed by NASA are also owned by the Citigroup military. Even on many warships, aerospace and automobiles, there is a space agency, in short, these two are a pair of pants.

Now I have found some sensitive data coordinates on the chip of another company, and these sensitive data coordinates are judged by the bigwigs on the scene, which are the extremely secret locations of their own country, and this satellite keeps talking in these secret places, so it goes without saying what the Citigroup military is thinking. In short, after the document came out, the level of dislike for the Citigroup military deepened again, and they also supported China even more, and banned Citigroup from participating in the exploration program for a year.

"Okay, now that we've found the evidence, then General Kelsen will do what you say, I believe that you are a 4-star general of Citigroup, and your words will definitely not be a child's play, right, then from the release of this information, that is, from today to next year, you will all be excluded from this exploration project. This is a joint decision, our decision, and your own consent, so from now on you have no right to make any further statements in this regard...... But of course, because you have put a lot of effort into building a military base over there, we will share some information with you, but sharing information does not mean that you have the right to explore that world, you can study this information carefully within this year, and when you explore that world again by this time next year, you will be able to do more with less. Since the matter has come to this point, Monk Chen stood up and made a final decision: "In this case, then is there anyone who has any opinions, if there are no opinions, we will implement this plan next." ”

"There is no opinion, we have no opinion, let's exclude Citigroup, this is also their own admission, they themselves said at the beginning, as long as they find information, let them rest for a year, then we will try to bring some information back to them, but this time I support China's decision not to allow them to participate in any action." ”

"That's right, we think it's the same way, Citigroup has already tested our bottom line, we don't want to explore with such teammates, we have had enough of other worlds in this world, if we still meet them in that world, God knows what kind of things they will do, we decided to seconded China's ban on Citigroup to participate in the task of exploring the world within a year- As I said earlier, we will try to bring some resources back to them to study the information of the other world, and we will try to copy as many as possible to them, hoping that they will be more sober after this time. ”

"In that case, let's get going, don't waste any more time, we can't wait to start exploring. ”

Monk Chen, as the leader of the project, after he spoke, all countries seconded it, and then everyone began to prepare to go. The door of the underground military base opened under the orders of Monk Cheng, revealing an all-metallic passage, which was full of technology, like a scene from a future sci-fi movie. As this passage unfolded, the lights inside lit up one by one, and then the guiding light strips with arrows on both sides began to flicker - as I said at the beginning, because in order to facilitate the handling of various things inside, this main passage was very wide in maintenance, and heavy equipment was allowed to execute in it, so it was basically a passage to the end, and after all the weapons were closed, it was a wide avenue.

The door had finally opened, and for the past year or two, everyone had been speculating about what was behind it, and in fact even if many people had gone in and explored, they had been brought in through other passages, and they hadn't even seen what the spatial door looked like. When entering that world to explore the outpost or build the outpost, they are all brought in under the blindfold, which seems to be a bit of a human right, but this is the basic condition to ensure that this secret is not leaked.

When the door is opened, everyone is looking in the grass gate, because this door leads to another world, and it is also the new hope of mankind, how to say, if there is no world behind this door, then it is likely that in the next one or two hundred years, the resources on the earth will be depleted and fall into serious involution, and at that time the interstellar travel plan of human beings does not know whether it has been completed, if it is not completed, then human beings will face extinction.

Therefore, this door is the key to the future survival of mankind, and the world behind it may be a new hope for human development, and everyone who enters this world at the beginning has an absolute advantage, when everyone has explored this world almost, and the second group of people comes in, then the first batch of people has occupied an absolute advantage - everyone knows this matter, so when building the outpost world base over there, almost every country contributed money and effort, and did not take into account the things behind at all. Because this matter cannot be calculated with a short-term mind, it must be looked at with a long-term vision, and the five pioneer countries that were selected this time have an absolute advantage, but unfortunately now there are not five but only four, because the remaining one is his own death.

General Kelson's face is now black and colorless, and the most well-equipped Citigroup soldiers on the scene also put on a confused expression that they have never had before - since the second world war, Citigroup has become the world's first power, and these soldiers are invincible wherever they go, but today seems to be different, and their next task ...... Can it still be executed?

"Next, you do what you have to do. Monk Chen didn't look at General Kelsen, whose face had turned black into coal, and said to Li Huan: "Bring our guests into that world, remember that after bringing them into that world, everyone must first register in our outpost, and only after completing the registration can you do other things." ”

"Then let's start entering that world next......" Li Huan nodded: "Everyone will enter the underground base with me." Remember that when entering the underground base, you can only go through the central passage, which means you can only go where is open to you, and I want to remind you once again that you have learned from the past, and I don't want anyone to be excluded from this exploration program. Because there are a lot of side roads in this underground passage that are not open to anyone - don't explore those paths, if we find someone intruding, then we will capture the identity of the intruder and will disqualify you from exploring. ”

"In addition, I would like to remind you that in the civilizations of that world, there are many people who are exactly the same as us, but there are also many who are different from us. Please don't make a fuss. There are people in the place where you go out, and it's also my private island, which is what I told you before, there are many humanoid races on my private island, which means that you may see some human-like but not human life, and I want you to respect them. ”

"In addition, in that world, within the limits of my private island and the territory of our country, the laws of our country are enforced, and I want you to be aware of this, and if the law is violated, we will be arrested and tried according to the current offender, and after the trial, we will be sent back to this world. In this way, you will lose the opportunity to explore, of course, we are not trying to connect the nine clans, and the criminals who are caught will only be sent back alone, but you should note that in the next year, all of you can only enter and exit once- That is to say, if someone goes crazy and dies on the edge of crime, then once they are sent back, your team will lose a talent, everyone is the elite of the elite, and they have received adaptive training and a lot of training, I think what it means to have one more person to explore that world, everyone knows it in their hearts, so don't die on the edge of crime. ”

After Li Huan finished speaking, he waved his hand: "Shangguan Han Dong, you take everyone in." Enter in an orderly manner and assemble before the portal. ”

"Okay, Brother Huan. Han Dong whistled: "Everyone come with me!" Just now Colonel Li Huan heard what he said, after entering this passage, don't look left and right, and don't be curious about what can be open to you The place has been opened, and the place that can't be opened to you, if you go to spy privately, you will be expelled from this team, and even affect your country, I don't want to talk about this kind of thing anymore, anyway, everyone follow us!"

After Han Dong finished speaking, with a wave of his hand, five hundred elite soldiers kicked and followed him, and the first batch entered the underground military base. Don't look at these Chinese soldiers, but they still haven't entered this very high-level base. In fact, until now, the base has been closed to outsiders at all, and there are strong secrecy measures, and everyone who works here before this has to sign a non-disclosure agreement - this non-disclosure agreement is for the project of all mankind, even outside the law. In addition to these secrecy methods, there are also a large number of surveillance equipment and self-transport weapons, and of course, the trump card among the trump cards in the end is the terrifying cultivator - with these things to protect this underground military base, it is almost never open to outsiders, and today they stepped into this base for the first time, and they all felt a sense of pride - because they were the first official dispatchers to explore the possibilities of humanity.

In this way, under the records of more than a dozen media that were invited to record this secret operation, our team was the first to enter the metal passage.

The phalanx of five hundred people kicked and walked in, but the whispers under the excitement could not be concealed.

"I heard that a year will pass as soon as it passes, do you think you can take leave to come back, I heard our chief say, that world seems to be the same as our world, and I heard those scientists say that there seem to be people who look like us over there, do you think I can find a girlfriend over there?"

"Don't talk about any girlfriends, as long as it's a single dog in any world, you can't find it in this world, do you still expect to find it in that world? Don't talk nonsense, I've also heard our chief say that that the world seems to be full of gold, you said that when we come back, can we come back with one or two pieces, if that's the case, then I can give my girlfriend a dowry!"

"It's impossible, don't think about it, our chief also said that going to that world is mainly to explore, and we must obey the commander's command, and we must not do what the commander does not let us do! You don't think about these fancy things, our task now is to explore that world, and then bring new hope for the survival of human beings in our country and the world - isn't this enough for you to brag? As long as we come back from the mission, we are all big heroes, and the problem of single dogs and not single dogs still exists at that time?"

"That's right, that's right, this brother is right, when the time comes, we will be the new hope of all mankind, and we will be the heroes of the world that has explored the new hope of mankind, and there will definitely be many girls who will throw an olive branch to us when they come back at that time...... But this brother looks at you very well, which unit are you from, why didn't I see you when I was on the training ground?"

"Hey, I'm from the Army Air Corps, didn't I come in for my brother? My brother's stupid guy broke his leg during training a few days ago, and he couldn't go, so I took his place...... I participated in an adaptation training, and now I am assigned to the third exploration team, brother, which unit are you?

"I'm a marine, it's okay, it's okay, everyone is a brother, everyone is an elite selected from the army, your senior brother is really unlucky, this kind of good thing hasn't been talked about, but I shouldn't say that, how to say it, now I'm so excited, we're all heroes when we come back, and our commander also said it, give me a first-class merit when I come back...... You didn't know that when I was chosen, and our chief was brushed down, his face was ......"

When the soldiers stepped into this base, walked to the metal passage, and walked towards the portal, the excitement could not be concealed, at first it was okay to whisper outside, but after entering the passage, the good sealing of the passage made the whispering sound heard by everyone, in the ears of Shangguan Qing, who led the team with Han Dong, these whispers affected our image!

"Okay, okay, what's the trouble, I know that you are all elites from various units, what's wrong? Aren't the elites of various units still being trained bitterly? Do you want me to release all the videos of your training a few days ago for you to watch again, or do you think the intensity of training is too low, if that's the case, after arriving in that world, I will ask Colonel Li Huan for a special courier to give you another training! Sweat more in peacetime and shed less blood in wartime, this is already the tradition of our army, how about it? Does anyone want to try it?" Shangguan Qing frowned and drank softly.

Although Shangguan Qing's voice was soft, the pressure it carried was extraordinary. Shangguan Qing is no longer the rookie she used to be, after she was brought into the ranks of cultivators by Li Huan, she began to cultivate by leaps and bounds, at first it was Li Huan who helped him find various resources and then helped Shangguan Qing improve, but after the exploration plan began, Shangguan Qing began to look for various cultivation discoveries and resources on his own, and now Shangguan Qing is already a cultivator of the fifth level of Qi cultivation- He didn't even tell Li Huan about this matter, when Li Huan was at the venue of adaptive training a few days ago, you only knew about it when you communicated with him, and after knowing it, you changed to a big economy, and his cultivation speed was simply amazing

A fifth-level Qi refining cultivator scolded with the sound of a piano with anger, that coercion was not trivial.

Shangguan Qing didn't even know about this matter until Li Huan was in the adaptive training ground a few days ago. After knowing this, Li Huan was greatly moved by Shangguan Qing's cultivation speed, and even caught up with his previous cultivation speed. You must know that Li Huan's previous cultivation was helped by Xiao Fei to expand his spiritual power, so he was able to break through the level so quickly. However, Shangguan Qun's cultivation speed has also improved by leaps and bounds without the help of tips - but it's normal to think about it, it's time to explore that world, although Li Huan personally said that the aura of that world is not very useful, only the spiritual power works, but in order to increase the victory rate, the country has invested a lot of resources without hesitation, and all the personnel cultivation this time has been continuously improved.

Even if the aura is useless, having spiritual power is a chance to win.

"This female chief is so powerful, how do I feel my whole body tremble when he speaks, this is the high-level cultivator our chief said? Oh my God, how did you say he cultivated so well, I think this chief is a little younger than me, he probably looks like he is in his early twenties, right? How can he cultivate such a skill? When do you think I will be able to do it?"

"Okay, okay, shut your mouth, this female commander is amazing, you haven't seen your senior brother visible and seen, everyone has to shut up when she gets angry, let's go forward honestly, don't embarrass us anymore, there are many reporters watching behind!"

"Yes, yes, we have to go in quickly, and there will be people coming in with us, and if we whisper, won't we lose the image of our country......?

Although the soldiers were still a little whispering, but the voice had been suppressed to the lowest, Shangguan Qin shook his head when he heard it, he also knew that in this kind of emotional turmoil, it was impossible to shut up everyone, anyway, it would be good not to say it too loudly, and anyway, it was not our country's army that was saying- After entering the metal passage, the army that followed behind was also whispering, and their voices were louder, and now this neat and clean metal passage echoed with the languages of various countries, at least seven or eight, I don't know where else, temporarily speaking in their native dialect.

Well, anyway, this is the first time to explore new hopes for human existence, and it's understandable that everyone is a little excited. Shangguan Qing laughed softly when she thought of this, looking at the hall in front of her that was getting closer and closer, and suddenly felt a little emotional.

That's what your own man is capable of.

Thinking back to the time when I first met Li Huan more than two years ago, he was still a person who didn't know anything in Panshi Island at that time. At that time, when Shangguan Qing saw Li Huan for the first time, he thought that he was a civilian foreign aid who specialized in technology. But in the following time, Li Huan continued to create miracles, which impressed Shangguan Qing, and even made Shangguan Qing feel that he would not marry this man - although he is now engaged, Shangguan Qing once thought that he was engaged in China, but he could go to other countries to be fair - Li Huan is probably the only man in the world who can make Shangguan Qing think like this.

In addition to his ability and charm, it is probably because Shangguan Qing still has Li Huan's blood flowing in his veins.

It is also to explore an unknown place, will Li Huan protect himself as much as before? This man's magical Shangguan Qun has experienced it personally, after all, Li Huan is now nominally his boyfriend. , Although Li Huan's relationship is a little messy now, how to say it, she thinks that Chen Xue is still a good friend, although Yu Ting doesn't deal with it, but she is not often there. And Li Huan's parents are also very good to themselves, so there is nothing to ask for, as for the final result...... Then leave it to heaven's will.

As a soldier, although Shangguan Qing often feels troubled by the love of her children, she also has a strong sense of honor and mission. After thinking back to these messy things for a while, she restrained her mood. The front has already arrived at the metal hall where the space door is placed, and at this time, all the automated weapons in the metal hall have been put away, because in the past two years, there have been scientific researchers entering and exiting from this space door to carefully explore the world, and don't forget that the contact point of this space door is under the castle built by Li Huan on Huayu Island, that place is absolutely safe, and when Li Huan left, he also specially instructed to take care of anyone who came from the space door. Therefore, after running a few times, the researchers resolutely removed all the weapons here.

Because everyone thinks that the people over there are too friendly, it makes no sense to put these weapons here, because Huayu Island is full of Li Huan's subordinates, and Li Huan made an order in advance, so that everyone can be friendly to the people who have crossed over. Therefore, after receiving preferential treatment over there, the researchers decided to cancel all the weapons here, of course, science is a rigorous attitude, like an unstable thing like a space gate, although there are no malicious creatures on the other side of the past this time...... But there is no guarantee that there will be no one every time.

Therefore, in this underground military fortress, the ultimate means of defense has not been withdrawn - that is, the four mechanical devices with radioactive signs placed around the space door of the metal hall.

Hydrogen, bombs.

Hydrogen bombs belong to a type of nuclear weapons. It mainly uses the energy released by the nuclear fusion reaction of hydrogen isotopes (deuterium and tritium) to kill and destroy, and is a powerful weapon of mass destruction. The five permanent members of the UN Security Council legally possess thermonuclear weapons, while hydrogen, bombs, at present, only China possesses.

The power of hydrogen bombs is much greater than that of atomic bombs, so why are we the only ones who have them today? In fact, there are not many countries in the world that can possess atomic bombs, and the explosion of hydrogen and bombs requires the use of atomic bombs as a guide, so a number of countries have already been eliminated from this threshold. The hydrogen bomb itself has very big defects, and it will cost a lot of money to maintain, and the storage time is still short. This results in a very large amount of waste. Therefore, the countries that have hydrogen and bombs have destroyed hydrogen and bombs one after another.

And we use a different hydrogen and bomb configuration from other countries in the world, so we have improved the shortcomings of hydrogen and bomb itself, so that the hydrogen and bomb have reduced the investment in maintenance by at least half. This configuration, known as the Yu Min configuration, is a technology developed by the father of our country's hydrogen bomb. At present, there are a total of 30 hydrogen bombs in our country, and the least powerful one can reach 3 million tons of TN, T explosion.

Four of the most powerful of these are in this metal room. This is the last safety bolt.

In the middle of the four hydrogen bombs is the portal that looks like it has and doesn't seem to have it, twisting into a circle of electricity in the air. No one knew what the theory of the portal was, but it looked like a ball of lightning anyway. But don't think about what kind of theory it is, because behind this door is the new hope of humanity. Let's put it this way, for example, he looks like a star lightning, and even if it looks like a septic tank, there are many countries that will throw the elite into it without hesitation.

"Okay, wait for the order here!" Shangguan Qing glanced back, a smile appeared on the corner of his mouth, and then raised his hand and shouted: "Everyone assembles in a team, waiting for the next order!"
