Chapter 540

Gu Lu rubbed his eyebrows while thinking about this question.

Obviously.

It is completely undesirable to simply increase the speed of operation and thus greatly reduce the coherence time.

Once the coherence time is reduced too short, the channel will be kept constant for a reduced time, which will greatly affect the performance of the quantum computer itself.

Therefore, while using qubit coding to improve the speed of operation, it is also necessary to pay attention to the length of coherence time.

But......

There was another obvious problem in front of Gu Lu.

When quantum computers operate at speeds of 100 picoseconds, this problem is not yet apparent.

However, when the operation speed is increased to the order of picoseconds through qubit encoding, the coherence time will be shortened to a fairly short time, which will further affect the performance of the quantum computer.

This stuff is troublesome.

It has to be handled with care.

Although the data parameter of 'coherence time' does not have the same significant impact on the performance of the quantum computer itself as 'speed of operation'.

But then again.

If the 'coherence time' is too long, it will not improve the performance of the quantum computer itself, but if it is too short, it will greatly affect the operation of the quantum computer.

Even when the 'coherence time' is shortened to a certain value, it will directly make the quantum computer unable to operate normally.

This is not the same as the 'operating speed' parameter.

For a quantum computer, the 'operation speed' is slow, and although the time to process the problem will be longer, it will still run smoothly.

But 'coherence time' is different, after this data parameter is too small, the quantum computer will directly strike.

To put it simply, the parameter of 'coherence time' is too long for a quantum computer to be useless, but too short is not good!

How to ensure that the operation speed of the quantum computer reaches the order of picoseconds, and at the same time, the parameter of coherence time does not affect the stable operation of the quantum computer, this is a big problem in front of Gu Lu!

In response to the problem in front of him, Gu Lu didn't think of any effective solution for a while.

…………

This side of the library.

Gu Lu was writing and drawing on a blank piece of paper, trying to deduce a reasonable solution to the problem.

But suddenly he felt a figure quietly approaching him.

Gu Lu subconsciously raised his head, and his gaze just met that of a girl with a red face.

The girl was obviously flustered, took a deep breath and barely calmed herself, then took out a notebook from behind her and put it in front of Gu Lu, "Uncle Gu, is it convenient to sign a name, I'm your fan?"

Signature?

Gu Lu, who suddenly realized something, looked around.

As far as the eye can see, there are pairs of curious eyes.

Around Gu Law's desk, there were nearly 100 students around, all staring at Gu Law with curious and inquisitive eyes.

Finished!

Gu Lu held his forehead, looking helpless.

Since the last time he and Uncle Ge experienced the energy of being watched by passers-by in the teahouse, Gu Lu has been very vigilant during this time and rarely appears in public.

But today, because he was in Yanda, Gu Lu lost this vigilance.

As everyone knows, Gu Lu's popularity and heated discussion among the students of Yan University are even crazier than most netizens on the Internet.

After all, Gu Lu is a teacher at Yan University.

For such a prominent figure in their school, many students have the idea of seeing it.

So, Gu Lu was tragic again.

Looking at the Yan University students who surrounded him on the inner and outer three floors, Gu Lu didn't know what to say except for a wry smile.

sighed in his heart, Gu Lu could only accept the bleak reality in front of him.

But fortunately.

Yan University's star-chasing behavior is still very rational, plus it is in a place like the library that needs to be kept quiet, there are not many people who want Gu Lu to sign it, most of them just watched for a while, saw Gu Lu's specific appearance and took a photo and dispersed.

After a few minutes......

Gu Lu looked at the crowd of onlookers in front of him, and subconsciously breathed a sigh of relief.

However, although there are fewer onlookers now, Gu Lu doesn't dare to stay in the library at all.

Gu Lu clearly heard in the conversation of several classmates that only the first batch of people came over now, and I don't know how many people are on the way to come!

Gu Lu doesn't have the hobby of being treated as a monkey in a zoo to watch and take pictures.

So, without any hesitation, Gu Lu took advantage of the lack of people and hurriedly packed up his things and slipped away.

"What about people, people, didn't you say that Uncle Gu is in the library?" The people who came from behind came over and looked around the library but didn't see Gu Lu's figure, and couldn't help but wonder.

"Uncle Gu has already left, everyone, you're late!"

"Uncle Gu's handsome photos are sold in the front row, four for one dollar, hehe!"

"Uncle Gu is really handsome, I thought he was handsome enough in the photo, but I didn't expect the real person to be more handsome, Mom, I'm in love!"

"Hehe, Uncle Gu is something you can covet, please touch your cup and speak. ”

"Professor Gu is a man who can only be obtained by those with a big heart!"

"Is that why you're a big man with 34D?"

…………

When "Where Are You Going, Uncle Gu" was being staged in the library, Gu Lu had already slipped back to the apartment with a stack of books.

In the study, Gu Lu was flipping through the book while conceiving the plan.

Gu Lu needed a solution, or a new way of qubit encoding, that could not only make the quantum computer's computing speed reach the order of picoseconds, but also ensure that the coherence time of the quantum computer would not drop too low.

Gu Lu's brain was running rapidly, and thoughts flashed through his mind.

Just when Gu Lu was immersed in the idea of the new plan and couldn't extricate himself, there was a knock on the door outside.

The knock on the door took a while to wake Gu Lu up from his thoughts.

Gu Lu hurriedly walked out of the study and went to the door to open the door.

As he walked, Gu Lu shouted, "Who?"

"It's me!" a familiar voice came from outside the door.

And the owner of the voice is none other than Bao Songquan.

Gu Lu hurriedly opened the door, "Senior brother, it's you!"

Bao Songquan nodded, "Well, I saw someone on the school forum that said that you appeared in the library, and I knew that you had come back today, I guess you will definitely not continue to stay in the library, most likely you will go home, now I guess right." ”

Gu Lu nodded and smiled bitterly, "That's right, I really don't dare to stay in that place in the library now, I didn't expect our students here at Yan University to be so crazy." ”

Bao Songquan knew what Gu Lu was referring to, so he patted Gu Lu on the shoulder and said with a smile, "Bear with me, after this period of time, when everyone starts school and has their own busy things, it is estimated that the heat will be reduced." ”
