We propose a hybrid entanglement concentration protocol based onquantum dots (QDs) and optical microcavity coupled systems. Thesystem is used for photon and electron hybrid entanglementgeneration. Also the proposed system can be used for parity checkwhich allows a quantum nondemolition measurement on the spin parity.By performing parity check process on electrons, the entangled statecan be concentrated into maximally entangled state efficiently.
Keywords:Quantum information; hybrid entanglement concentration; quantum dot; micorcavity
