Humanity is missing, luckily I have billions of clones

With these heavy spacecraft as the last resort, Li Qingsong finally truly devoted all his energy, brainpower and resources to promoting scientific and technological development.

This is truly an all-out effort, racing against time, and not daring to waste even a second.

Five years, just five years. For an ordinary electroweak civilization, five years may not be enough time to complete the preliminary project establishment work of a major scientific research task. But for Li Qingsong, including quantum supercomputing, the number of technological breakthroughs he needs to achieve is as high as tens of millions!

Every minute and every second is so precious.

With Li Qingsong's full efforts and with the material support from dozens of planets larger than that of tens of thousands of transport ships shuttling back and forth, countless factories roared all day long, churning out equipment and boxes of consumables, which were then all put into an almost endless number of experiments.

Some do nothing but lie in bed and think, some contribute their brainpower, some take care of the daily life of these clones, some implement the Skynet plan, some ensure that industrial production and scientific research are not disturbed, some maintain industrial production, some mine minerals, some work on the front line of scientific research, some manage the operation of various factories...

And so on and so forth, a total of 1.02 billion consciousness connections are connected to the clones at all times.

The clones still need to rest for a period of time every day, but Li Qingsong has never rested for a minute.

In the quantum laboratory, millions of first-line clones are distributed in various research fields, concentrating on their work.

To study quantum computers, the first problem to be solved is the stability of quantum bits.

A pair of entangled quantum particles are easily affected by external interference, resulting in the loss of the entangled state. This is the decoherence process.

To maintain stable operation, the decoherence problem must be solved.

A truly practical quantum computer requires a very high number of quantum bits, which makes it exponentially more difficult to maintain stability.

After preliminary theoretical research and actual experimental verification, Li Qingsong finally decided to solve this problem from these aspects.

The first is the research and development of new superconducting materials.

In low-temperature environments, superconducting materials are not rare. There are too many common materials in reality that will enter a superconducting state when the temperature drops to a certain level.

But this material is not suitable for quantum computers because in addition to the requirement of superconductivity, it has too many other requirements, such as toughness, ductility, photosensitivity, etc.

All conditions must be met.

Following the materials science principles accumulated over the past years, Li Qingsong continues to carry out research and development of new materials with atomic-level precision.

In addition to materials, Li Qingsong must also find a sufficiently powerful quantum error correction method to accurately identify the quantum bits after they are accidentally disturbed and decoherent, eliminate their impact, and reduce error accumulation.

Quantum error correction algorithms are completely different from ordinary electronic computer algorithms. This is not just a mathematical job, but also involves very basic physics principles.

In order to study this set of algorithms, Li Qingsong had to simultaneously start a large amount of basic physics research, using particle colliders to continuously collide and study the changes of particles under extremely high energy levels. At the same time, in high-temperature laboratories, he raised the temperature of particles to hundreds of billions of degrees Celsius, or in high-pressure laboratories, he used diamond anvils to extremely compress the gas, even to the point of compressing it to the same level as the core pressure of the earth, in order to obtain data on the movement and changes of particles.

In addition to the error correction algorithm, Li Qingsong must also make a breakthrough in another aspect.

Low temperature refrigeration technology.

Quantum computers can only operate stably at extremely low temperatures, even close to absolute zero.

Normally, refrigeration should not be an obstacle for Li Qingsong.

After all, the space environment itself is extremely cold, and refrigeration technology has long been mature.

In the laboratory, Li Qingsong has long been able to produce temperatures only one trillionth of a degree higher than absolute zero, and has observed a large number of new physical phenomena in such a low-temperature environment.

However, quantum computers are large in size, and require the cooling of a macroscopic object. At the same time, this macroscopic object is constantly running and generating heat. So, from an engineering point of view, although the temperature requirement is only 1K, which is much higher than the low temperature produced in the laboratory, the difficulty is actually higher.

To this end, Li Qingsong had to carry out extensive research on laser cooling, magnetic evaporative cooling, and Bose-Einstein condensation to find a suitable way to cool down quantum computers.

At the same time, Li Qingsong also had to study extremely precise laser low-temperature manipulation technology.

The essence of quantum computers is the manipulation of quantum bits to enable them to perform calculations, and the means of this manipulation is laser.

Because the object of manipulation is quantum and must be carried out at extremely low temperatures, the requirements for the accuracy and reliability of the laser controller are extremely high.

Li Qingsong must develop extremely precise light sources and controllers to overcome this difficulty.

These problems are just a general classification. In reality, each problem can be broken down into thousands of small topics, each of which requires a large number of people to study, and different topics may be interconnected, making the problem as complicated as a tangled mess.

But at this moment, Li Qingsong didn't even have time to feel fear in front of this seemingly insurmountable obstacle like a mountain, nor did he have time to think about how difficult it would be to overcome this obstacle.

No matter how hard it is, just do it.

This is equivalent to the scientific research strength of ten ordinary electro-weak civilizations. Just like Yugong who moved the mountains, they have devoted all their efforts to this task.

Time slowly passed as Li Qingsong gave his all.

When one problem is solved, a new one will emerge. When a new problem is solved, a newer one will emerge, and it seems to be endless.

But Li Qingsong's investment of brainpower and resources will never end.

Solve as many problems as they come, no matter how many problems will arise in the future, just do it!

In almost just a moment, four and a half years passed quietly.

Looking at the huge equipment in front of him, which occupied the entire hall and consumed up to 100,000 kilowatts of energy, a smile finally appeared on Li Qingsong's face.

The key breakthrough was achieved before the originally scheduled five-year period was up.

Now, a practical quantum supercomputer has finally been built by our own hands!
