Scientists from the Shanghai Institute of Microsystems and information technology at the Chinese Academy of Sciences have developed a magnetometer based on an array of superconducting quantum interferometers, which can detect submarines at a distance of several kilometers, rather than hundreds of meters. This will allow the Chinese to control fully the waters of the South China sea, which caused serious concerns in the United States.
Chinese submarines detector uses technology called superconducting quantum interferometer SQUID (Superconducting Quantum Interference Device), which scientists have combined into an array. The action of the interferometers based on the laws of quantum mechanics: their sensitivity to magnetic fields hundreds of times higher than normal, and is on the verge of a background magnetic field.
Magnetometers detect a submarine as a kind of anomaly in conditionally exactly the Earth’s magnetic field, but the range of their actions is small. The use of quantum technology greatly increases the sensitivity of such a detector, but together with the desired signal it will be caught and an infinitely large amount of noise, including the echo of solar storms. In his time in the United States and are unable to solve the problem of filtering out interference, but in China, seems to have reached a positive result.
At least so argued in the Chinese press, but some days all mention of it disappeared from public sources. It was reported that scientists have fashioned a whole array of quantum interferometers and SQUID have developed an algorithm that compares their evidence and ignores extraneous objects and obstacles, concentrating only on submarines.
