Quantum radar
Encyclopedia
Quantum radar is a hypothetical remote-sensing method based on quantum entanglement.
One possible implementation of such technology has been developed and patented by defense contractor Lockheed Martin
. It intends to create a radar system which provides a better resolution and higher detail than classical radar can provide.
The technology is hoped to work by using photon entanglement
to allow several entangled photons to function as if a shorter wavelength was used to allow detection of small details while having an overall longer group wavelength that allows long distance transmission.
According to a recent and controversial (but not yet known to have been disproven) theory, any such remote-sensing device (including, but not limited to Lockheed Martin's planned implementation of technology), using quantum (photon) entanglement, may be able to extract meaningful information from specific regions of hyperspace.
A hypothetical research paper on the subject suggests that photon-entanglement, combined with interferometry, can possibly be used to remote-sense distant quantum properties of past, present or even future hypersurfaces of spacetime. The paper is based on exploiting causal and relativistic loopholes supposedly found in the 1999 realization of the Delayed Choice Quantum Eraser
experiment by Yoon-Ho Kim, R. Yu, S.P. Kulik, Y.H. Shih, designed by Marlan O. Scully.

Photon entanglement
This brief explanation of photon entanglement is a supplement to the article Bohr-Einstein debates and is designed to help clarify the discussion of the Einstein-Podolsky-Rosen argument in quantum theory which takes place in that article.-Entanglement:...

Delayed choice quantum eraser
A delayed choice quantum eraser, first performed by Yoon-Ho Kim, R. Yu, S.P. Kulik, Y.H. Shih, and Marlan O. Scully, is an elaboration on a quantum eraser experiment involving the concepts considered in Wheeler's delayed choice experiment...
