After arriving at a place, planting maple trees is the tradition of the imperial people to continue the Liuyun Town in the Qingquan era, and a few brothers in the family will plant a few maple trees, and the two He Jingfeng brothers will naturally plant 2 maple trees.

But if you think that these maples are traditional maples, this kind of maple trees are a new type of maple tree specially researched and developed by a company within the empire using genetic recombination technology.

It is characterized by strong adaptability, as long as it is on a living planet, it can almost 100% survival rate; It can grow very tall, luxuriant, very ornamental, this kind of symbolic maple, naturally can not be thin, small and few leaves.

There is also this kind of maple tree that grows very fast, although it cannot be said to be faster than those super fast-growing trees, but it is also more than ten times faster than traditional maple trees, and it only takes a few years to grow into a towering tree; In addition, this maple tree is genetically sterilized, and all the trees used to be brought to the alien planet for planting are sterilized by funds, and they cannot reproduce the next generation, in order to protect the ecological environment of the planet!

In the interstellar era, nothing is simple, and this maple tree, which integrates biotechnology technology, is called the "Legacy Tree" within the empire! ”

After planting the inheritance tree, He Jingfeng was worried, the population of the Canis Major Galaxy here is only tens of millions, and when it is distributed to each planet, the population is very scarce, and his family's 20,000 acres of land can't even think of how to develop it for a while.

The land is vast and sparsely populated, almost every household has a huge amount of land, and everyone is worried, and He Jingfeng is the same, driving a flying machine to fly slowly over his territory, wanting to find something special.

"The land is good land, flat and fertile good land, but unfortunately I can't find any bright spots to develop! Now it seems that only a few cash crops can be grown. He Jingfeng shook his head worriedly.

……

The Milky Way, the solar system, the imperial capital star Venus, Liu Qingquan woke up from sleep early, and his long-term biological clock was very punctual and woke up on time.

Look at the beauty in her arms, because the throne was passed to her son, she has been obedient to herself for this period of time, and has unlocked countless postures that she didn't dare to think of before, which made Liu Qingquan say that she couldn't stand it.

"Well, after this position was passed out, I had a lot of leisure, and I was a little unaccustomed to it!" Liu Qingquan rested his head on his hands and looked at the beautiful scenery outside, the sun was shining, the birds were singing and the flowers were fragrant, it was a good day!

"Zhou Jingbo seems to say that there is a new progress in quantum computers, well, let's go to see where he is today!" Liu Qingquan seemed to have thought of something, and was about to get up quietly, tiptoeing for fear of disturbing the beauties around him.

"Why did you go early? Don't want to move again? "I didn't know that the beauty around me had already woken up, and when she saw Liu Qingquan tiptoeing, she grabbed it and said charmingly.

"You damn ~ demon ~ elf, I'll let you know how good I am today!" Liu Qingquan looked at the grace of the beauty half-covered and half-exposed, and was ready to be furious, so that the other party could feel the thunder and rain!

On a bright morning, the sound of the enchanting sounds of heaven evokes infinite reverie!

At 9 o'clock in the morning, Liu Qingquan came to the Quantum Research Institute of the Imperial Academy of Sciences refreshed, as the most important branch of the Imperial Academy of Sciences, the Quantum Research Institute covers a very large area, with many research offices, more than 1,000 large and small research laboratories, and hundreds of thousands of large and small scientific research staff.

"Boss, you're here just in time, I have a problem here and I'm trying to ask you."

Zhou Jingbo, who was concentrating on the experiment, accidentally saw Liu Qingquan coming, and hurriedly came over, although the research work of quantum computing has reached the final point, but there are still some major topics that have not yet been overcome, since this time, Zhou Jingbo is almost sad and can't eat, as soon as he sees Liu Qingquan coming, as if he saw a savior, he came over!

"Look at you, you're getting old, how can you say that you are also a national treasure of the empire now, pay a little attention to your image!" Liu Qingquan saw Zhou Jingbo's hurried appearance, shook his head and said.

"Boss, it's not that you don't know my temperament, no matter how old I am, I'm stronger than a 20-year-old boy now, and it's not a problem to kill a tiger!"

Zhou Jingbo pursed his lips, cultivating the scientist's special Yuan Force Method, and Zhou Jingbo has been cultivating since he graduated from college and entered Qingquan Technology, and his age is quite good, so his progress has been good, and he looks no different now than he did decades ago.

"Boss, our quantum computer research work has progressed to the final step, but until now, there is still a very headache!"

Zhou Jingbo is a workaholic, and without saying a few words to Liu Qingquan, he will directly enter the topic.

"Well, what do you want to hear?" Liu Qingquan nodded, compared to those who like compliments, Liu Qingquan still prefers Zhou Jingbo's vigorous and resolute style, this is what a scientist should have!

"Both quantum parallel computing and quantum analog computing essentially make use of quantum coherence. Unfortunately, quantum coherence is difficult to maintain in real systems. ”

"In a quantum computer, the qubit is not an isolated system, but interacts with the external environment, resulting in a decay of quantum coherence, known as decoherence (also known as "decoherence"). Therefore, a central issue for quantum computing to become a reality is overcoming decoherence. ”

Zhou Jingbo began to slowly explain the problems encountered in his work, you need others to answer your questions, you need to slowly explain all the causes and consequences of the matter, and Zhou Jingbo is like this at this time.

"We used a myriad of methods to eliminate quantum decoherence, and eventually we found that quantum coding is the most effective method found to date to overcome decoherence."

"The main quantum coding schemes are: quantum error-correcting codes, quantum error-avoidance codes, and quantum error-proofing codes. Quantum error-correcting code is an analogy of classical error-correcting code, which is the most studied type of code, which has the advantage of a wide range of application, but the disadvantage is that the efficiency is not high. ”

When Zhou Jingbo descended here, he stopped a little and asked Liu Qingquan to absorb the things in front of him first.

After Liu Qingquan listened to Zhou Jingbo's words, he kept calculating the other party's thoughts in his mind, and the well-informed Liu Qingquan naturally knew what problems they had encountered at once.

A quantum computer, as the name suggests, is a machine that enables quantum computing. To clarify quantum computing, let's first look at classical computing. A classical computer can be physically described as a machine that transforms an input signal sequence according to a certain algorithm, and the algorithm is implemented by the computer's internal logic circuitry.

Classical computers have the following characteristics; The input and output states are both classical signals, which are described in the language of quantum mechanics, that is, the input and output states are the eigenstates of a certain mechanical quantity. If you enter a binary sequence 0110110, use a quantum notation, i.e., |0110110>. All input states are orthogonal to each other. It is not possible to input the following superposition state for a classical computer: c1|0110110>+c2|1001001>.

Each step of the transformation inside a classical computer evolves into an orthogonal state, while ordinary quantum transformations do not have this property, so the transformations (or computations) in classical computers correspond to only a special set of classes.

Corresponding to the above two limitations of classical computers, quantum computers have been generalized separately. The input of a quantum computer is described in terms of a quantum system with finite energy levels, such as a two-level system (called qubits, and the transformations of a quantum computer (i.e., quantum computing) include all possible positive transformations.

Therefore, the characteristics of quantum computers are as follows: the input and output states of quantum computers are general superpositional states, and they are usually not orthogonal to each other;

The transformations in a quantum computer are all possible positive transformations. After the output state is obtained, the quantum computer makes certain measurements of the output state and gives the calculation result.

It can be seen that quantum computing has greatly expanded classical computing, which is a special type of quantum computing. The most essential characteristics of quantum computing are quantum superposition and quantum coherence.

The transformation of each superimposed component by the quantum computer is equivalent to a kind of classical computation, all of which are completed at the same time and superimposed by a certain probability amplitude to give the output of the quantum computer. This type of computation is called quantum parallel computing.

Quantum computers have very obvious advantages over traditional computers; Quantum characteristics may break through the limits of existing classical information systems in terms of improving computing speed, ensuring information security, increasing information capacity, and improving detection accuracy.

A 250-qubit memory (made up of 250 atoms) may store up to 2 to the 250th power, which is more than the total number of atoms in the universe currently known.

Attacking existing cryptography with quantum search algorithms, classical computing requires 1,000 years of computation, while quantum computers only need less than 4 minutes.

The quantum key system uses quantum states as the information carrier, and its security is guaranteed by the principle of quantum mechanics.

Based on the quantum teleportation process, multi-terminal distributed operations can be realized to form a quantum Internet.

……

"Are you worried about how to improve the efficiency of quantum coding?"

Although quantum computers seem to be simpler than quantum bubble bombs and quantum communication, in fact, quantum computers are very powerful, but its calculations are countless times more complex than quantum communications and quantum bubble bombs.

The technology contained in quantum computers itself includes quantum communication technology and quantum bubble technology, and also involves countless other related new quantum technologies, and it is not as simple as ordinary people think!

ps: I recommend a fantasy novel with no lower limit, which is written about all the fantasy characters who suddenly descended into the real world, including novels, comics, movies, games, myths and legends of fantasy characters, the world has become chaotic, and the chaos of various fantasy characters has begun. This book is called "The Great Fantasy of the World"! (To be continued.) )
