How far is the all-optical quantum computer from us?
How far is the all-optical quantum computer from us?
The online English website reported that physicists at the Munich University of Technology in Germany have recently made breakthroughs in the field of precise control of light source technology at the atomic thickness level, and humans have gone further from quantum chips. By introducing optical communication inside the chip, the Internet will be faster and more secure.
Scientists at the Munich University of Technology point out that, unlike electron-dependent information, photons can achieve faster speeds, lower power consumption, and quantum entanglement. This technology can immediately detect the listener, and can automatically close the key in real time, so that hackers can not get started.
Based on the three-atom-thickness luminescent layer of the semiconductor material molybdenum disulfide (MoS2), scientists use a cesium ion beam for radiation to achieve better control of the light source. Based on such a technology, a quantum sensor or a quantum communication chip for a smartphone can be produced.
In Japan, scientists at Osaka University have also realized laser-encoded transmission of electron-spinning states based on quantum dots, thus solving the problem of unstable entangled states in the past. This is considered a major step in the vector subnet.
Engineers at Stanford University in the United States have also found ways to bind photons in nano-sized silicon materials (Nature Magazine July 24). Light-emitting photonic tubes based on this technology allow light to travel in only one direction (similar to optical isolators, but not to the first device). Unfortunately, it is not possible to implement a miniaturized device.
Dr. Mark Lawrence, who invented this method, pointed out that people's vision is to achieve a plenoptic computer that is photon rather than electronically driven for all information processing and transmission.
IT giants including Alphabate, Intel, Microsoft, etc. are actively developing quantum computers, and some startups such as Rigetti have begun to enter the field. Of course, China is not in the world. The question now is, how far is the all-optical quantum communication from us? How will it change our technology?
