Complete deterministic multi-electron Greenberger-Horne-Zeilinger state analyzer for quantum communication
Hai-Rui Wei, Bao-Cang Ren, Mei Zhang +2
We present a scheme for the multi-electron Greenberger-Horne-Zeilinger (GHZ) state analyzer, resorting to an interface between the polarization of a probe photon and the spin of an…
Single-photon-assisted entanglement concentration of a multi-photon system in a partially entangled W state with weak cross-Kerr nonlinearity
Fang-Fang Du, Tao Li, Bao-Cang Ren +2
We propose a nonlocal entanglement concentration protocol (ECP) for -photon systems in a partially entangled W state, resorting to some ancillary single photons and the parity-c…
High-efficiency multipartite entanglement purification of electron-spin states with charge detection
Tao Li, Bao-Cang Ren, Hai-Rui Wei +2
We present a high-efficiency multipartite entanglement purification protocol (MEPP) for electron-spin systems in a Greenberger-Horne-Zeilinger state based on their spins and their…
Complete hyperentangled-Bell-state analysis for photon systems assisted by quantum-dot spins in optical microcavities
Bao-Cang Ren, Hai-Rui Wei, Ming Hua +2
Bell-state analysis (BSA) is essential in quantum communication, but it is impossible to distinguish unambiguously the four Bell states in the polarization degree of freedom (DOF)…
Optimal multipartite entanglement concentration of electron-spin states based on charge detection and projection measurements
Bao-Cang Ren, Tie-Jun Wang, Ming Hua +2
We propose an optimal entanglement concentration protocol (ECP) for nonlocal N-electron systems in a partially entangled pure state, resorting to charge detection and the projectio…
