China will be the data protection pioneer in the quantum computing giant leap

Quantum computers are the current serious agenda of leading tech companies from Google to Alibaba in China. is These computers will have much more processing power than today’s computers. Of course, great potential risks will also occur following this technological leap. The powerful computers of the future have the ability to break encrypted information. This ability threatens everything from billions of dollars of money in the world of e-commerce to the secrets of people and governments on the Internet.

Definitely, the big players in the processing world will have a solution for this problem. One of their solutions is to use cryptography based on the same technology and scientific-physical concept, i.e. quantum. Another solution would be to implement quantum-based security protocols that would neutralize the decryption capabilities of future machines.

Competition It is considered one of the serious missions of government intelligence agencies to implement strong security solutions. In the world of quantum computing, the competition is closely followed and almost everyone is a contender; But in the field of quantum security cryptography, the Chinese have stolen the lead from their competitors to some extent. Currently, the Chinese government is conducting extensive research in various fields of frontier technology, such as Artificial intelligence is on the agenda. Quantum processing is another frontier technology that was included in the priorities of this government.

Duncan Earl, a former researcher at the Oak Ridge Institute and the director of technology at the quantum company Quibitekk, about this great leap in Chinese technology and research. He says:

China has a calculated strategy to own this technology. If we want to wait another five to ten years to enter quantum technology, we will definitely fall behind in the competition.

Quantum processing is defined based on quantum mechanics. This type of mechanics is a science that investigates the strange behaviors caused by changes in very small particles of matter. In traditional computers, information is stored in bits in transistors. In these computers, each bit represents zero or one. In fact, these bits are the basic pieces of data that are called computer tasks.

Some types of matter behave differently when they are very small. This difference allows the quantum bit, or qubit, to store a combination of zeros and ones. In fact, two qubits are capable of storing four values ​​simultaneously. When the number of qubits increases, the power of a quantum computer increases greatly. It is worth mentioning that the government of Dubai cooperates with Microsoft in implementing quantum solutions.

Solutions must be designed to deal with the excessive power of quantum decoding

Quantum encryption, like quantum processing, is based on the irrational behavior of very small particles. The codes that secure the data are sent by photons. Photon is the smallest particle of light. With these new methods, it becomes possible to detect tampering or intrusion into data using appropriate equipment and resources. Ultimately, if these methods are implemented correctly, they become nearly impossible to decipher.

There is still no guarantee that quantum network cryptography will perform over long distances. Of course, if this is possible, China’s serious plans to test these technologies, as well as the allocation of government, academic and financial resources for them, will have many benefits for this country.

China has invested millions of dollars in testing quantum networks. Their tested networks transmit data using quantum encryption. Last year, a Chinese satellite called Micius made a video call between Beijing and Vienna using quantum cryptography. Another development of this company in the field of quantum processing is the implementation of a communication network of this type between Beijing and Shanghai. This network was implemented after four years of research and development.

Currently, quantum cryptography can only be implemented at certain intervals. The video call project between Beijing and China increased this distance to about 7,500 km. Of course, in terrestrial communication, the use of optical fiber networks is suggested, which are currently in a range of about 250 kilometers.

The Chinese Micius satellite attracted the world’s attention more than all China’s efforts to advance in quantum encryption. . University of Science and Technology of China was a state university that was in charge of implementing this project. This university also has a project to implement terrestrial networks, which will probably increase the limits of these networks to about two thousand kilometers.

Currently, quantum communication There are distance limits

The authorities of Anhui and Shanfong provinces, through which this optical fiber network passes, invested a total of eighty million dollars in this project. In fact, this project, like other major infrastructure projects in China, received extensive government support.

The communication line created for this huge project will be extended to other cities and regions. By 2030, China’s goal is to implement a network that distributes quantum cryptographic keys around the world.

Chao Yang-lu, professor of physics at the University of Science and Technology of China, who was present in this project, is one of these experts hoping for a quantum network.

In traditional networks, people and organizations have the ability to intercept and access information with the purpose of eavesdropping in every part of the information transmission path. In other words, governments can enter the line of communication at any stage of communication. In an interview about his project, Professor Luo says that only a few vulnerable points remained in this network for about 2,000 kilometers:

We know that this method is considered a primary solution. In fact, the final solution has not yet been provided; But this stage was also a great progress in the security issue.

In front of the Chinese government, the United States and its industry are standing. Of course, their view of quantum cryptography is only slightly beyond the laboratory level. Instead, American researchers are trying to develop more advanced cryptographic algorithms capable of dealing with quantum computers using ordinary mathematical methods. As a result, this technology does not require new infrastructure.

Eric Hay from the QuantumExchange team

Qubitekk is an American startup in Southern California that aims to increase the security of the electric grid in The Tennessee region is using these new technologies. Another startup called Quantum Xchange is developing a quantum crypto network in the Northeast region. This startup aims to provide services in this field to Wall Street banks and other large companies. Researchers at Stoney Brook Nair University are working on the establishment of a third company active in this field. It hasn’t done much in this field

The clear point is that small American startups, such as Qbitek, definitely do not have the ability to compete with China’s millions of dollars of ready-made infrastructure for quantum cryptography. Furthermore, many experts believe that great achievements occur in research laboratories. In the context of this laboratory research, the US Department of Energy is preparing an experimental network in Chicago, which is considered similar to the systems implemented in China.

About the organizations Collaborating with these startups, Los Alamos and Oakridge laboratories are working with Qbitek. QuantumExchange is also moving its equipment to 60 Hudson Street. This area was the old hub of Western Union, which today operates as the internet hub of Lower Manhattan.

University of Chicago Quantum Lab

QuantumExchange is developing a quantum cryptographic link between Manhattan and New York, which aims to connect the major banks of these two regions. Of course, the ultimate goal will be to expand this network to the northern and southern regions of the east coast of America.

Other research centers, such as the University of Chicago, are working on more advanced projects aimed at producing quantum amplifiers. These devices, known as Quantum Repeaters, increase the range of quantum cryptographic networks. This topic says:

We haven’t reached the final goal yet. Of course, we hope that the goal will be achieved in the next few years.

Quantum communication methods require new hardware. This hardware includes fiber optic broadband and even new satellites. In addition, there is a need for devices capable of detecting optical photons.

David Ashalom

Qubitek works on quantum cryptographic networks; But it still does not have special light detection devices to perform this task. The startup buys the detectors from a small manufacturer in New Jersey. In April this year, this business manufacturer sold its devices to a Chinese company called RMY, and as a result, the startup Qbitek faced a lack of resources.

Of course, the Chinese company promised to deliver devices to Qbitek; But some time ago he announced that due to problems in the production of new devices, it will not be ready until March of next year (corresponding to March 2017). Other big and small manufacturers and teams in the world are busy making these devices; But currently, Americans feel the lack of hardware to advance their projects.
