Development of 'quantum radar' which can be easily captured even by stealth aircraft goes on worldwide

"Stealth technology" which prevents reflection of radar waves by special shapes and surface painting makes it harder for enemies to capture their existence "stealth technology" occupies a very important position in recent defense of national defense. However, the new radar technology "Quantum Radar" being studied in various countries is thought to be able to find even such a stealth machine easily.

A radar capable of knowing the distance and direction to the object by emitting a radio wave to the object and measuring its reflected wave was put into practical use by the British Army in 1941. After that, not only as an important method for the enemy (Sakki) who knows the situation of the enemy but also the radar is being used to protect the safety of the aircraft and the ship.

On the other hand, the quantum radar which is being studied is a phenomenon in which a force like telepath works between two photons that are distant from each other "Quantum entanglement"By using the phenomenon of light called" knowing the existence of an object in a remote place. " When a photon irradiated to the object is influenced by the object, it appears also in the photon whose change was left at hand. In other words, since the quantum radar does not have to observe the reflection of the signal wave, it can surely know its existence in any high-performance stealth machine.

This research is conducted all over the world, and at the Tamagawa University quantum information science laboratory in Japan, studies of quantum radar strong against bad weather such as fog and rain are progressed by using light called "squeezed light" It is.

Research is also progressing in China, and there seems to be no doubt about the research of quantum radar that can capture even the stealth fighter "F 35". There is no doubt that if the ultra-high performance radar based on a completely new concept is deployed in actual war, not only in China, the way in which armaments are themselves will change dramatically.

Even if Japan deployed the F35 it can be easily found and tracked by "quantum radar" China (September 26, 2016) - Excite News

Quantum radar research is also underway at Waterloo University in Canada. Professor Jonathan Bar, who is at the Institute for Quantum Computing (Quantum Computing Laboratory) of the same school, said, "In the Arctic Ocean, the climate of the universe like magnetic storms and solar flares has a major impact on radar observation "It may be difficult to recognize things." "By transitioning from conventional radar to quantum radar, not only is it to solve such a noise problem but also to recognize the object designed to prevent being captured It is desirable to be able to do so. "

However, the quantum radar is still at a level where it can be reproduced in the laboratory. Mr. Bar says, "The goal is to be able to refine the quantum in" entangled state "enough to catch the object by pushing the button." The Canadian Government is investigating this field with a budget of C $ 2.7 million (approximately 230 million yen) for the All Domain Situational Awareness (ADSA) Science & Technology Program belonging to the Ministry of Defense.

The US and Canada, facing Russia across the Arctic Ocean, operate the North Warning System, a defense system consisting of 54 radars covering the area of ​​Newfoundland Island from Alaska. However, it is said that this radar is due to expire in 2025. Mr. Bar says, "This project will enable technological development to advance quantum radar from laboratory level to practice, which will change our mindset on defense."
