Robust quantum repeater with atomic ensembles against phase and polarization instability
arXiv:0903.1977 · doi:10.1103/PhysRevA.79.042301
Abstract
We propose an alternative scheme for quantum repeater without phase stabilization and polarization calibration of photons transmitted over long-distance channel. We introduce time-bin photonic states and use a new two-photon interference configuration to robustly generate entanglement between distant atomic-ensemble-based memory qubits. Our scheme can be performed with current experimental setups through making some simple adjustments.
