Quantum Radar became reality

The F-22 aircraft is very well known to the people about its stealth, there were no radar that could detect it but that was done by a conventional radar where the microwave was sent by the transmitted and when it gets reflected by the object it is sensed and the object is located but if the signal is weak or the object uses certain technique to scatter the microwave attacking on it the traditional radar becomes useless.
A new Quantum Radar which was one thought to be fictious has been created by the scientists and engineering in the University of York under the guidance of  team led by Dr Stefano Pirandola, of the University's Department of Computer Science and the York Centre for Quantum Technologies, a double cavity device which converts the microwaves into optical waves that are propagated in search of objects.
A nanomechanical oscillator is used for the conversion of microwaves into optical waves, and the optical wave consist of two waves which are strongly correlated with each other, the techniques used is that one wave is directly sent to the receiver and the other is sent in search of an object and of there is anything struck by the wave in its path it is reflected back (even high stealth object reflects very low level of radiation) to the receiver and where it meets the first wave, the defector senses the difference in level of photons of the two waves and this makes it possible to know about the object.
Despite of being a radar technology Dr Stefano Pirandola says that this technique can be used in mri(magnetic resonance imaging) scans where the radiation level will be reduced for the patient and in spectroscopy of proteins and dna.
