Chapter 1176

What happens if the power is not attenuated during transmission?

What if a computer has exponential speed and perfect accuracy?

Professor Duncan Haldane once gave a standard answer to this question. And in the fall of 2016, the physicist and two other colleagues won the Nobel Prize in physics this year for "discovering the topological phase transition and topological phase of matter"!

In short, through rigorous experiments, they found that even the smallest micro materials can show macroscopic properties and have topological phase.

This sounds a little difficult to understand. If you want to understand it, you have to understand the concept of topology.

As we all know, mathematicians often look at problems in a different way than ordinary people. They are used to seeing essence through phenomena. Topology is such a subject, which studies some properties of geometry or space that can remain unchanged after changing shape continuously.

One of the most classic examples is that for a topologist, doughnuts and coffee cups all look the same because they all have a hole.

Because there is only one hole, you can turn the doughnut into a coffee cup through a smooth deformation process, and vice versa Even though it may seem incomprehensible or even inexplicable to ordinary people, in fact, because of this mathematical method, scholars in other fields have found many interesting things.

Especially in the field of physics and materials, many amazing discoveries in the 1980s originated from the method of topology and provided the theoretical basis.

But for a long time, although people are used to applying topology to solve the problems of the macro world, they have no idea whether topology can be used to deal with subatomic particles such as electrons and photons.

Because they are all affected by the peculiar laws of quantum physics, their size, position and even shape are in an uncertain state.

However, the 16-year Nobel Prize in physics has given a positive answer to this proposition.

Even these subatoms in the micro world conform to the characteristics of topology!

This theory obviously has no influence on our daily life, but for the field of electronic engineering, it really opens the door to a new world!

In the wonderful quantum world, these properties show amazing stability and some remarkable characteristics in a particular stage of matter. The most typical example is topological insulator.

Especially in graphene materials, this feature directly led to the birth of SG-1 superconductor and carbon based chip.

At the same time, this property also promotes the research of quantum computing.

According to the principle of quantum computer, information can be stored in something called qubit by the property that subatomic particles can be in different states at the same time. It is precisely because of this characteristic that quantum computers can solve problems exponentially compared with traditional computers.

However, the problem is that the subatomic particles that store data are very fragile. Unlike stable atoms, even slight perturbations may change their states.

In quantum mechanics, the so-called "decoherence" - any environmental impact may lead to the collapse of entangled state of quantum bits!

To solve the problem, either noise reduction, anti-interference, or both, no matter which technology route is adopted, subatomic particles must be stabilized.

This is also one of the core problems in the research and development of quantum computers.

At the same time, it's also a subject that has been studied by land boats these days

Jinling Institute of higher research, laboratory on the third floor underground.

The empty room, originally used as a spare sample room, is now being filled with a large number of newly purchased equipment.

This includes multi-functional physical property measurement system, step meter, vibration sample magnetometer, high and low temperature magnetoresistance tester, and in-situ freeze dryer, etc. Although not the luxury of the lineup, it can also be said that the sparrow is small and dirty.

In addition, in addition to the necessary equipment for the research of carbon materials, there is also a UV curing 3D printer with the highest precision up to 8 microns, which is mainly used to print the plastic mold needed for experiments.

A thumb sized film was carefully placed into the magnetron sputtering atomic layer deposition equipment. The boat carefully compared the data on the experimental table and set up new experimental parameters on the computer.

Having finished all the work, he finally felt relieved and hit the enter button on the keyboard.

The green light came on and the equipment in the laboratory began to work.

With coffee, he went back to the office chair beside him and sat down. Lu Zhou looked at his watch and was thinking of using something to pass the boring time. At that time, AI controlled the UAV to come here.

AI: Master! Just for a moment! What a surprise! φ (≥ ω ≤ *)?]

the line of sight is focused in the air in the first half meter of the small TV, and the boat raises the lower eyelid, which is said by accident."You upgraded?"

AI: [eh? You all know?! Σ (° Δ° ||) ︴]

land boat: "..."

Is this guy upgraded or demoted

Sighed in the heart, the land boat ignored it, closed his eyes and entered the system space.

As a branch of system task, the experience accumulation of artificial intelligence is synchronous with that of informatics. Just as AI's level rose to lv4, his informatics level also rose from lv4 to LV5.

At the moment of upgrading, you can see the dialog prompt even if you don't enter the system space

【…… ]

[g. informatics: LV5 (0 / 300000)]

confirmed the attribute panel after the change once, and the boat felt its chin thoughtfully.

Indeed, as he speculated, the accumulation of progress bars can be accelerated by observing various behaviors of players in the virtual reality world. In other words, the experience needed by the branch of artificial intelligence is actually a kind of sociological experience?

However, at present, Lu Zhou doesn't pay much attention to AI. After entering the system space, he just takes a look at his property panel and the progress bar of branch technology, and then turns his consciousness back to the real world.

Opening his eyes, I saw that the small TV that was staring at the four rotors had been shaking in front of him for half a day.

AI: Master, don't you praise AI? (* / Omega *)]

land boat: "well, well done."

AI: how perfunctory! QAQ]

“…… It's almost time. "

Pretending not to see the dialog box on the small TV, Lu Zhou looks down at the time on his watch and mutters to himself.

As if to confirm his words, the signal light jumped from green to red on the instrument not far away.

See, the boat immediately ordered the way.

"Ai, turn on the in situ freeze dryer."

AI: [copy! Although she was extremely reluctant to do so, Xiaoai obeyed.

I just don't know if it's his illusion. I always feel that the little guy's reaction seems to be more and more emotional Or, in other words, more and more human?

It's not a good thing whether it's a good thing or not.

at the end of the day, the way AI processes information is totally different from that of human brain. One is that emotion is determined by logic, the other is that emotion dominates logic.

Maybe its existence will give birth to a new species, maybe?

Of course, it's too early to say that.

As its "Guardian", Lu Zhou can only say his own responsibility and take a step by step.

At least in terms of current performance, the little guy is quite obedient, playing the role of a little assistant in life and research, and absolutely obeying his orders without discount.

My worry seems to be a little superfluous?

With the help of Xiaoai, Lu Zhou transferred the samples from the magnetron sputtering atomic layer deposition equipment to the in-situ freeze-drying machine, carried out the freeze-drying treatment on the carbon based chip samples, and then carefully observed the film-like chip with the help of the metallographic microscope, and recorded the experimental data on the book beside.

Now he has more than 30000 points. According to the system's price, 120000 points are needed to exchange a full set of quantum computer technology.

In fact, however, there is a lot of moisture in this valuation.

If we divide the problem into two parts, on the basis of those problems that have been solved by the academic community, we can reduce 80% or even more of the points consumed by the unsolved problems!

So far, he has spent 20000 points to overcome several key bottlenecks in the research, and the rest is his understanding of carbon materials, Mott insulator and mayorana fermion, through consulting some previous research results, and on this basis, he has completed some promotional work.

For example, the topological insulator carbon material including the mayorana fermion, and the superconductor layer with a single atom width superimposed on it without affecting the stability of the mayorana fermion.

In this special topological phase material, subatomies can be protected.

In other words, the quantum bits formed under this topology will not be changed due to some small or local interference. It is far more stable than the general qubit, which can make our quantum computation more accurate and efficient to deal with the problem of the answer we want.

These works have saved at least 100000 points for the land boat.

It's these jobs that give him the chance to use points on the blade.

This is also a reflection of "knowledge is power".

Carefully completed the last step of all the test work, the land boat put a layer of translucent graphene thin as cicada wings on the prepared circuit mold.It's like looking at a perfect work of art, with a heartfelt smile on his face.

"Performance tests met expectations."

"It's perfect to look good!"

“…… Sure enough, mayorana fermion is the perfect choice for making quantum computers! "

The rest is to verify the efforts of these days and whether the 20000 points he spent are worth it.

Pressing the power button, the heart of the boat almost reached its throat.

It was almost a moment.

At the same time that he pressed the button, the preset program finished running on the film. The signal processed and output by the logic circuit is transmitted to the display screen, and soon a line of clear characters appears on the display screen -

[Hello world]

looking at the characters bouncing on the screen, Lu Zhou's heart suddenly rejoices, his fist is tightly squeezed, and he almost doesn't jump up excitedly.

"It's a success!"

Subconsciously, he shouted out the excitement in his heart, and as a result, Lu Zhou was frightened by his own behavior and hurriedly checked the operation of the equipment.

When we saw that the stable operation of the "thin film" chip did not cause the "quantum bit entangled state collapse" due to the cheering of more than 80 decibels, the face of the land boat finally showed a heartfelt and reassuring smile.

It seems that this time

It's really done!
