A new "quantum radar" device uses entangled microwaves to overcome the limitations of traditional radar systems.
The device, constructed by a team of the Institute of Science and Technology Austria, is capable Noise in radar, according to MIT Technology Review . Though still in early stages, researchers say the quantum radar's low energy levels could lead to better noninvasive medical imaging techniques or stealthier military technology.
The trick behind this new radar is to use quantum entanglement instead of the radio waves used in radar.  ArXiv earlier this month.
While the act of reflecting and detecting the photons as they bounce off whatever they are spotting destroys the quantum entanglement, MIT Tech Review the photons are still associated with each other 1
