Improved Probabilistic Quantum Teleportation By Repeated Generalized Bell State Measurement
Year: 2019
Type: preprint
Abstract: We propose a scheme of probabilistic quantum teleportation (PQT) in which Alice possesses both qubits of the entangled resource and makes repeated generalized Bell state measurement (GBSM) on the pair of qubits, consisting of (1) the qubit of information state and (2) one of the two entangled resource qubits (taken alternately) until quantum teleportation (QT) with perfect fidelity is indicated. Alice then sends to Bob, the qubit not used for last GBSM and also the result of this GBSM and Bob applies a suitable unitary transformation to replicate exactly the information state. We calculate the success probability upto 3rd repeated attempt of GBSM and plot it with concurrence of the entangled resource state.
