Hybrid entanglement concentration using quantum dot and microcavity coupled system

Hybrid entanglement concentration using quantum dot and microcavity coupled system We present two hybrid entanglement concentration protocols based on quantum dots (QDs) and optical microcavity coupled systems. The system is theoretically analyzed and used for photon and electron hybrid entanglement generation. Also, the proposed system can be further used for parity check that allows a quantum nondemolition measurement on the spin parity. By performing parity check process on electron spins, the entangled state can be concentrated into maximally entangled state efficiently. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals

Abstract

We present two hybrid entanglement concentration protocols based on quantum dots (QDs) and optical microcavity coupled systems. The system is theoretically analyzed and used for photon and electron hybrid entanglement generation. Also, the proposed system can be further used for parity check that allows a quantum nondemolition measurement on the spin parity. By performing parity check process on electron spins, the entangled state can be concentrated into maximally entangled state efficiently.
