Optical generation of many-spin entangled states in a quantum well

Mostrar todas las versiones(2)

A quantum-mechanical many-particle system may exhibit non-local behavior in that measurements performed on one of the particles can affect a second one that is far apart. These so-called entangled states are crucial for the implementation of quantum information protocols and gates for quantum comput...
