Scientists create and test quantum radar

Austrian scientists have succeeded in creating and successfully testing a quantum radar that uses the principle of quantum entanglement. Further enhancements and integration of radar into the modern world could dramatically change areas such as biomedicine and safety.

How quantum radar works

So, quantum entanglement is nothing more than a physical phenomenon, as a result of which two particles remain connected and endowed with common physical parameters. Moreover, the distance between them can be different.

Austrian professor J. Fink together with American, British and American colleagues showed a completely new principle object detection - microwave quantum illumination that functions on entangled microwave photons.

At the same time, the created prototype quite easily detects objects in highly polluted thermal conditions, in which conventional radars are practically blind.

Principle of operation

In fact, the principle of operation of the new radar is quite simple:

Initially, a group of photons is taken, which is entangled and a pair is obtained - signal and idle.

Then the signal photons are sent to the emitted object, and measurements are made above the blanks in relative isolation (isolated from interference).

Of course, after the signal photons return, there is already there is no such strong connection, but by the residual correlation, scientists have learned to determine the location object.

At the same time, having performed generation at a temperature of -273.14 degrees Celsius, the scientific group was successfully able to find objects with extremely low reflectivity at room temperature.

What are the prospects for invention

Despite the fact that this installation is only the first laboratory prototype, the scientists assure that the installation is ahead of classical radars in many respects.

For example, when there is a power shortage, classical radars are practically blind and with great difficulty distinguish between reflections of objects from background noise. Quantum radar works much better in such conditions.

The engineers also believe that their invention will find active use in biomedical devices and security and tracking systems.

Well, as they say, wait and see.
