Great breakthrough in information security, British scientists invented a new quantum chip

According to foreign media reports, foreign scientists have invented a new Quantum chip. With this technology, today's smart phones will become more secure and the computing power of personal computers will reach an unprecedented level. The new Quantum Chip R&D team, headquartered at the University of Bristol in the United Kingdom, is expected to announce this invention to the outside world at this week’s British Science Festival.

It is reported that in the short term, the technical team will mainly apply this technology in the field of information security. For example, through this technology, the user's mobile phone can better withstand the invasion of hackers, making people more secure in mobile phone shopping and bank transfer.

While the industry is eagerly looking for a way to better solve the problem of Internet communication security, quantum communication technology is considered to be an important basic and supporting technology in the next-generation information and communication field because of its high transmission efficiency and absolute security. Quantum communication, in particular, has the absolute security that traditional communication methods do not have, and it has significant application value and broad application prospects in key areas where national security, financial services, and Internet communications require high information security.

Quantum technology has always been the dream of the scientific community. Quantum chips made of silicon are much smaller than the glass passivation diode chips we commonly used before. Therefore, after mass production, this technology will make the current mobile communication more reliable and the speed of computer operation will also be greatly improved.

Jeremy O'Brien, professor of physics at Bristol University, believes that "quantum technology has the greatest advantage of being perfectly compatible with existing electronic devices." O'Brien said that it is entirely possible that quantum technology will completely replace traditional microelectronic circuits in the next 3 months to 5 years. Antti Niskanen, director of the Nokia Research Center at Cambridge University in the United Kingdom, said: "The development of photonics and quantum electronics has opened up a vast window for the development of information encryption, sensors and mobile security. With the continuous improvement of the security of personal data and the continuous improvement of mobile phone functions, smart phone users in the future will also benefit from it."

Since quantum chips use the same manufacturing process as conventional chips, volume production is not a fantasy. In addition, with the same long-wave frequency, the new quantum chips will be compatible with existing fiber and other infrastructure. Mark Thompson, deputy director of photonics and quantum science at Bristol University, said: “The current global communications network, including the Internet, is driven by fiber optic cables. Fortunately, our latest research can be compatible with these carriers. In other words, they speak the same language." At the same time, the development of quantum science has opened the way for the realization of quantum computers. A quantum computer is a brand-new computer based on quantum theory. Unlike traditional computers that use binary or triodes, quantum computers use qubits and can be in multiple states at the same time, instead of just being at 0 or like a traditional computer. The binary state of 1. In view of this characteristic, information that can be stored and processed by quantum computers is beyond the reach of traditional computers. “It's like the wind tunnel is no longer suitable for aircraft simulation, but it starts with computer simulation. In the future, I believe that also the academic community will begin to use large-scale quantum calculators instead of traditional chemical laboratories for the simulation of chemical experiments. "Professor O'Brien said finally.
