Hyperentanglement concentration of nonlocal two-photon six-qubit systems via the cross-Kerr nonlinearity

Abstract We present an efficient hyperentanglement concentration protocol (hyper-ECP) for two-photon six-qubit systems in nonlocal partially hyperentangled Bell states with unknown parameters. In our scheme, we use two identical partially hyperentangled states which are simultaneously entangled in p...
