Quantum radar will make stealth technologies inefficient

<pre>Quantum radar will make stealth technologies inefficient

Already in the near future stealth technologies will become less effective. In fact, thanks to the project of the Ministry of Defense of Canada to create a new quantum radar. The cost of the project is $ 2.7 million.

The project is led by Jonathan Boug of the Institute of Quantum Computing of the University of Waterloo (IQC). The work of the new radar is based on the principle of the phenomenon of quantum entanglement to eliminate strong background noise. As a result, the detection of invisible aircraft becomes a reality.

 Quantum Radar

The main problem of conventional radar is that the detection of the target is related to the signal-to-noise ratio, that is, the signal reflected from the target is always accompanied by random extraneous noise. To select a signal, it is necessary to increase the radar power, which inevitably leads to an increase in noise.

The essence of the concept of quantum entanglement boils down to the fact that if the electrons, photons or other quantum particles are tangled (tangled) with each other, then the connection between them persists even if they are diluted to different ends of the universe.

Quantum radar uses so-called quantum illumination, which filters out noise, causing outgoing photons to identify the radar signal using the quantum entanglement principle. As a result, the photon from the transmitting antenna of the radar, while keeping in touch with its pair, filters out the “foreign” photons of the reflected signal. Thus, background noise and electronic interference are eliminated, and the mark from the target on the radar screen becomes clear enough to detect even the most modern aircraft manufactured by stealth technology.

The quantum radar developed by IQC is currently undergoing a laboratory testing phase, but it is hoped that it will one day become a real operational radar.
