3 Feb 2016 | | Abstract: | We present a bidirectional modification of the standard one-qubit
teleportation protocol, where both Alice and Bob try to transfer their quantum
states to each other using single Bell state and auxiliary (trigger) qubits.
Three schemes are under consideration: the first, where action of parties are
governed by two independent quantum random triggers, the second with single
random trigger, and the third one as a mixture of these schemes. We calculate
the fidelity of teleportation for all schemes and find the minimal amount of
correlation between trigger qubits to overcome the critical value. An amount of
symmetrically transmitted entanglement between parties is also analysed. The
suggested scheme of bidirectional teleportation can be realized using current
experimental tools. | | Source: | arXiv, 1602.1420 | | Services: | Forum | Review | PDF | Favorites | |
