Chapter 103 - Quantum Computer

Hearing this question, Oliver felt some headache, how could an astronomical problem involve a supercomputer? He deeply felt the intricate connection between the various disciplines and the lack of human depth. Such a deficiency is almost all-round.

The path of development of science has never been a straight and well-traveled road, but rather intertwined paths, with many intersections between the various paths.

Mathematics is the most basic subject, and then only upward into physics, chemistry, biology, etc., and then there are more different branches.

Because of the small population, many seemingly less important branches of science and technology simply no one to study, which is a great pity that people. A large number of papers are kept within the Noah's database, quietly waiting for someone to dig.

Countless branches of science will actually promote each other, or each other constraints, for example, a breakthrough in chemistry, will have an impact on materials science, and materials science will affect engineering and so on.

Oliver believes that in a few years' time, the whole of human technology will change dramatically under this pattern of technological explosion.

Computer science should be considered a relatively basic discipline.

Nowadays, many jobs cannot be done without the support of computers, such as the automation of the Genov factory, the control of unmanned excavators, etc., all need supercomputers for background control. And almost all science and technology, need modeling analysis and large-scale computing. This means that whether it is solving equations, fitting, or finding approximate solutions, faster and more powerful computers are needed.

So Noah's most powerful central computer has always had applications for use.

This situation is actually not too good, because the central computer must keep part of the computational volume, monitoring a large number of instrumentation facilities to ensure that the Noah's safety issues.

In response to these problems, Oliver has long wanted to replace the faster, more powerful computer.

But the current computer technology has reached a bottleneck, Noah almost all rely on the old bottom to support. Now these supercomputers have not been updated for many years, the calculation speed has been almost unable to keep up with the times ...

About the next generation of computers, people also have many kinds of research directions, such as biological computers, quantum computers and so on.

The biological computer sounds too fantasy, the most reliable or quantum computer, because it is the most realistic and most likely to achieve.

In the past, some countries on earth have already achieved the entanglement manipulation of 10 light quanta and have accumulated a lot of research experience. According to Oliver's understanding, after all these years, there should be a breakthrough in this area.

For this kind of scientific progress, Oliver usually does not convene a council, so as not to waste everyone's time. He chose to go directly to Yuriko's research institute, Yuriko has always been very clear about the details of the major research institutes, and I do not know how she did it.

Oliver walked all the way there, while meditating on the details of quantum computers in his mind, so that he would not be ignorant and be ridiculed by some people for no reason.

The upper limit and potential of a quantum computer is much higher than the classical computers currently used, because its computing power is incremented exponentially.

The entanglement manipulation of 10 light quanta means that this quantum computer can do 2 of 10 operations per step, which is 1024 operations.

1024 times, such an amount of calculations sounds garbage, and is not a big deal. Even an ordinary person's cell phone has hundreds of millions of calculations a second.

But as long as there are more light quanta to manipulate, its computational speed will rise exponentially!

When it reaches 50 light quanta, the quantum computer will be able to perform 50 calculations of 2 in one step, which is equal to 1125899906842000, i.e. one thousand trillion calculations, which has already reached the computing power of the "Tianhe K" supercomputer ranked fifth by Noah.

When it reaches 60 light quanta, its computing power, will be able to step on all the classical computers!

When it reaches 100 light quanta, the calculation speed of each step is up to 2 times 100! At this point, the entire Noah's classical computer combined is a dud, not nearly as much as a fraction of a quantum computer.

What about 200, 300, or even 1000 ...10000 quanta of light?

Ten thousandth of two? That's an unimaginably astronomical number!

"You think too simply, theoretically, the quantum computer computing capacity can indeed be infinitely increased, but in practice is more difficult." Yuriko gave him a faint look and interrupted Oliver's daydream.

"The quanta in a quantum computer must be in a state of entanglement with each other in order to work. And the greater the number of light quanta, the less stable the entangled state will be. Our technology can't get thousands of photons entangled at the same time ..."

"To get light quanta to entangle, it is best to do so in a vacuum as well as in a superconducting environment, which involves quantum dots, NMR, quantum optical circuits, superconducting rings, etc. ..."

Yuriko spat out a bunch of proper nouns, leaving Oliver feeling clouded.

He had been in a great headache about the esoteric quantum theory.

He asked directly, "Just tell me straight, can we make a quantum computer with a higher computational capacity or not?"

This undemanding attitude made Yuriko despise it very much, and she gave Oliver a white look: "... can, with our technology, at most 30-50 light quanta can be entangled at the same time and manipulated properly."

Oliver felt a little dissatisfied, 50 light quanta, too little, right? Such a quantum computer is no better than the central computer!

Only to hear Yuriko continued: "... However, we once removed a broken computer from the inside of the flying saucer, you remember, right? That was the quantum computer."

"We can try to repair it, but we have to use the few flying saucer materials ..."

Speaking of which, Yuriko pulled a quick pile from her computer, "The Lakewood Supercomputing Center once tried to repair this broken computer. They made this report, you can take a look at it ..."

"A gravitational wave telescope is a flying saucer build, does the computer have to be a flying saucer build too?"

Oliver sounded a little upset, took the report, just glanced at the same, and suddenly his face turned a little blue.

This damn, most of the requirements are extremely high performance superconducting materials and electromagnetic materials, but also found in the flying saucer stuff! This is not to die? They are firmly controlled by the major laboratories and are important research specimens.

If they rashly asked to hand them over, the scientists would have to go crazy!

"Do we have to have these materials?" Oliver asked with a frown, as if he could see himself being scolded. Scientists are fierce, but do not care what your status is, the scolding as usual.

"Of course, we can also use our own human materials, but the performance is not good." Yuriko said faintly: "You should also know the barrel theory, as long as there is a short board, the overall speed will also be dragged down."

"Okay, I get it." Oliver said with some irritation.

The gravitational wave telescope was a flying saucer creation, and even the supercomputer was also a flying saucer creation ... compared to human technology was dregs, which gave him a rather discontented feeling.

The use of flying saucer artifacts gives everyone a sense of insecurity, because people have not figured out exactly how it works, for scientists, unknown things are always uncomfortable to use.

The security of a civilization can not rely on what others ... give an example, the Indian defense computer always can not be made in the United States, the Earth Alliance people's engines can not always be provided by Russia. The analogy is the same with the Noah, for scientists who are very reluctant to use such things that are not well understood.

Using these flying saucer creations means instability and unreliability, and even if an error occurs, one does not know about it and it is difficult to correct it.

Well, actually, it was also Oliver who was in too much of a hurry, humans didn't even have a year to figure out how to reach the level of flying saucers.

But this time the situation is different, even if they are dissatisfied, there is no way, survival is the most urgent problem of a civilization, no supercomputer, you can not use the gravitational wave telescope, no gravitational wave telescope, it is difficult to monitor the alien spacecraft ...

Now, people can only blindly believe in flying saucer creation once, because only with human technology, the detection of green light ships are still in a state of limbo.

This is a matter of survival, the survival of civilization is the first priority. The action of building a supercomputer he was imperative.

That's it for today's update, good night friends. If you have a recommendation, throw some votes, thank you! This volume of the Mars chapter will end in two weeks, there are any suggestions you can mention, I will see.
