Quantum Disentanglement Eraser: an optical implementation using three-photon spontaneous decay

Quantum Physics 2015-10-28 v3

Abstract

The 'disentanglement eraser' or 'entanglement restorer' scheme allows retrieving entanglement by erasing the information about the formation of a classical (or separable) state. It suggests an analogy between the pairs of properties: entangled-separable and wave-particle, the latter as described in the 'quantum eraser'. The scheme illustrates the physical importance of information in quantum systems, and it is also useful as a building block for quantum computation. An optical setup for its simple implementation using three-photon decay in a centro-symmetrical crystal is proposed.
