Physicists Just Built The First Working Prototype Of A ‘Quantum Radar’
Quantum entanglement – that strange but potentially hugely useful quantum phenomenon where two particles are inextricably linked across space and time – could play a major role in future radar technology.

> In the case of the radar, one photon from each entangled pair, described as a signal photon, is sent towards an object. The remaining photon, described as an idler, is kept in isolation, waiting for a report back. If the signal photon reflects from an object and is caught, it can be combined with the idler to create a signature pattern of interference, setting the signal apart from other random noise. As the signal photons reflect from an object, this actually breaks the quantum entanglement in the truest sense. This latest research verifies that even when entanglement is broken, enough information can survive to identify it as a reflected signal.
This looks interesting.
