Ruan Lin retracted his gaze and turned his head and walked back to the Titan:

"wit, let's start laying the base, we want to colonize the three terrestrial planets Cc, Cf, and Ce."

All three planets are in the habitable zone of Gliese 667C, and they are all very close to each other and are not approaching their Rocky limits.

If a large star smashes into one of the planets and causes it to change its orbit dramatically, all three planets will be destroyed if the Loch limit of two of the planets is reached.

Ruan Lin ordered: "WIT, start laying the base first, and then carry out mass production of the planetary environment modification device, and after the production is completed, it will be put into the other hemisphere and the other two planets!" ”

The flat area of these three rocky planets is very small, and there is no need to take care of it, so it can only be modified with this device.

The price is simply to wait for decades.

Paying only the price of time is what Ruan Lin is most willing to bear.

Robots from planetary-class destroyers begin to land on the surface one after another, and they will temporarily transform the landscape in this area, and then build one base after another.

If there are billions of robots, it is extremely unrealistic to modify the landscape of three rocky planets, they are not asteroids.

Nguyen Lam named the project the Millennium Project. This galaxy has been its "home" for thousands of years.

"WIT, all your computing power is used for the planetary transformation project, and I will conquer the quantum-photonic computer myself."

Ruan Lin's consciousness returned to the Titan, and since leaving the solar system, the research on the quantum-quantum computer of the Titan civilization has not stopped.

Human beings in the earth age are mainly biased towards the research of quantum computers, mainly because the light source efficiency of photonic computers is too low, the volume is too large, and the process complexity is high, resulting in too expensive prices, and the light source integration of photonic computers is more difficult.

To use an analogy, a quantum computer = a manned space rocket, and a photonic computer = an aircraft traveling in the stratosphere.

The so-called "quantum superiority" means that for a specific task, a quantum computer can solve it at a rapid pace.

And no classical computer in the age of Earth, using any known algorithm, could not be completed in an acceptable time.

At the same time, the simulation and thrust reversal ability of quantum computers is also incomparable to other computers.

Although the computing power of the photonic computer is not as good as that of the quantum computer, its advantages mainly lie in the fact that it can use photons as the carrier to transmit information, replace electronic hardware with optical hardware, replace electrical computing with optical computing, and form an integrated optical path by optical fibers and various optical elements.

This is the quantum-photonic computer, which still requires some wiring, but still retains the advantages of both.

Ruan Lin also consulted information about the Earth period, and in 2053, this idea has already been proposed.

Ruan Lin decided to change the entire Titan into the "brain" of the entire civilization, and after the computer was built this time, the interior of the Titan would be filled with computers.

The best way to protect it is to moor it in the Tianhe, and if it encounters an irresolvable crisis, it can start the short-distance jump engine as soon as possible.

Under Ruan Lin's instructions, a laboratory soon appeared not far from the Titan.

However, the experiment was delayed for more than 4 years, and it took more than a year to collect fabrication materials, and the rest of the time was spent building the main machine.

Looking at the behemoth in front of him, Ruan Lin finally breathed a sigh of relief.

Ruan Lin renamed it "Optical Quantity Computer", and although the name is very similar to "Optical Quantum Computer", the technological gap between them can be described as "worlds apart".

The main body of the optical computer is 10 meters wide and 7 meters high, and the "small black room" is still installed outside, but the amount of liquid nitrogen that needs to be supplied has been greatly reduced, and the internal temperature only needs to reach 100K to ensure the peak computing speed of the optical computer, which is actually the advantage of the photonic computer.

Internally, most of the complex circuitry of the original quantum computer has disappeared, replaced by various lasers, lenses, and nuclear mirrors.

This time, the light computer can only be regarded as an imitation product.

Although he can't make a condensed version of the host of the Titan civilization, Ruan Lin is already very satisfied with being able to build this epoch-making product.

After all, it would be unrealistic to ask apes to read how modern computers are made and let them make identical products.

"WIT, my commissioning phase will take decades to go on, so don't bother me if there's nothing particularly important."

After Ruan Lin finished communicating with WIT, he immediately threw himself into the debugging work of light quantity calculation.

In fact, the difficulty of optical quantum computers is "how to ensure the fidelity of a single quantum logic gate while ensuring the low distortion of photon transmission." ”

In the first experiment, Ruan Lin encountered a big problem: quantum coherent superposition conflicted with photon transmission, and the computer could not recognize the calculation.

This is also the most likely problem in Ruan Lin's imagination, after all, the combination of the two is very incredible.

Ruan Lin "compartmentalized" the photons, and after they were transmitted, they arrived at a laser, where the data was further analyzed, and the quantum coherent superposition calculations were performed again, and the photon computation part did not stop during this time.

Mistakes took place for 16 years, and the previous research during the voyage was only on paper, and it was only after the actual production that the difficulty of the technology became known.

In the 19th year, the test of the light computer has not stopped, and the solution of the two-dimensional Ising model, which arranged 1,000 results, took only one Planck time length.

The optical computer is about 1.2 million times faster than a quantum computer, and what started as a permutation code problem is now like a 1+1 for it.

Wit sighed in his consciousness: "About this study. . . It started from leaving the solar system! It bears witness to the course of our entire planetary civilization. ”

"Thank you, Titan."

In the 22nd year of the experiment, there was no longer much of a problem with the optical computer, and the next work was to build another one for WIT.

Ruan Lin returned to his body, and he opened the door to the laboratory.

The light of three stars greeted you, and the perceived temperature at this time was about 23 degrees Celsius.

And around, a number of refining bases stand on the surface, countless robots are busy outside, directly laid on the surface of the robot production line crazy operation, although they do not know what "civilization" is, but they are all fighting for the entire earth civilization.

The surrounding surface is no longer a rugged hill, and even if you look into the distance, it is a flat river.

The oxygen levels around it are almost indistinguishable from those of Earth, which is also the result of the planetary environmental modification device.

"Wit, I'm done, we'll be able to do the computer replacement later!"

Ruan Lin also showed a relieved smile.

"Dr. Nguyen, congratulations. Here I would like to report to you about the faint signal received 1 Earth month ago. ”
