Chapter 647 (2/2)

When some people thought that no one would buy it, they were disappointed soon.

Shortly after the announcement, the Institute of high temperature plasma of the Chinese Academy of Sciences announced the purchase of 25kg helium-3 for research on controlled nuclear fusion technology.

Immediately after that, Russian officials announced that they would buy 5 kg helium-3 from the flying ant Space Center. The Russian official voice has just been settled. The island official also announced that they would buy 5 kg helium-3.

The two countries announced the purchase of flying ant space company, Europe and India are not willing to lag behind, also sent to buy 3 kg of helium-3. Even Yiguo came to buy 2kg.

If it wasn't for the amount of helium-3 they needed, they would almost start snapping it up.

Shortly after the announcement of the purchase, several countries kept silent. The U.S. officials, who often targeted the March ant group, also came to buy 10 kg of helium-3.

For ordinary people, 311 million kg is very expensive, but for tritium fuel currently used to study controlled nuclear fusion, the price is half the price, which is simply a good price.Several countries that are studying controlled fusion technology have not missed this opportunity.

Helium-3 is the main fuel of controlled fusion technology in the future. They need to use these fuels in advance to study controlled fusion technology. With enough fuel, their research and development speed can be doubled.

In just half a month, the company made nearly 12 billion.

Now it's just that the controlled nuclear fusion technology has not been fully popularized. In addition to the two controlled nuclear fusion power stations that have been put into operation in the world, the rest are all experimental equipment.

If the world popularizes the controlled nuclear fusion technology, establishes hundreds of thousands of controlled nuclear fusion power stations, and runs them day and night, then the flying ant Space Center's revenue of selling helium-3 is enough to scare people.

In the quantum lab, Chen Mo is waiting for the results.

The preparation of entangled states and coherent manipulation of multiple qubits is the core of quantum computer.

Chen Mo uses the cavity quantum electrodynamics system to prepare the quantum entangled state. Quantum bit manipulation is relatively difficult. There are many kinds of particle systems in quantum entangled state. No matter which particle is used, there are very high requirements for the control and measurement of entangled particles.

Now there are superconducting materials, using electronic quantum state is his best research and development path.

In quantum bit manipulation, Chen Mo uses the method of superconducting quantum interference to manipulate the quantum.

To design the electrodynamic quantum control system of the superconducting quantum dot device, we can control the electronic state of the quantum dot by fine adjusting the electrode to interfere with the electron.

Quantum chip design, integrated measurement readout system of superconducting single electron transistor.

Superconducting chip is one of the solutions of solid-state quantum computing. Its advantage is that it has good scalability in technology, can integrate more quantum bits and improve the computing power of quantum computer.

”The results of the experiment come out.”

While Chen Mo is waiting quietly, Mo Nu opens her mouth.

A simulated image of the experimental results appears on the platform. The coupled resonance image, the simulated quantum dot, is located at the intersection point. This image is the random walk of qubits in the superconducting chain.

Mr. Chen quickly focused on other data.

The maximum and minimum control errors are in the range of 10 ^ - 6, and the fidelity is as high as 99.99%. This control accuracy has far exceeded the threshold value of quantum gate control accuracy required by fault-tolerant quantum computing.

This result shows that the experiment of 16 qubits is successful.

After checking the data, Chen Mo was satisfied.

In the right way, we can gradually expand the controllable quantum quantity.

The technology requirement of quantum chip is not high. The superconducting transistor chip of micron level can realize the main frequency logic circuit of gigahertz level. The key lies in the number of quantum bits that can be controlled.

Quantum computers can manipulate up to 50 qubits, which is comparable to the current supercomputers.

If the number of maneuverable quantum can reach 100, the computing power of quantum computer can reach 1 million times of the total computing power in the world. Its terrible computing power can make any difficult password of traditional computer be cracked in a moment.

Quantum computer is a real parallel computing computer. As the number of controllable quantum bits increases, the computing power increases exponentially. When the number of controllable qubits reaches 1000, the computing power of quantum computer is almost infinite.

This is the necessary tool for the next information revolution after the age of artificial intelligence internet.

”Go to the next experiment.” After confirming that there is no problem, Chen Mo asks Mo Nu to start the next experiment.
