Two-Way Quantum Communication in a Single Optical Fiber with Active Polarization Compensation

  • Conference paper
Book cover Quantum Communication and Quantum Networking (QuantumComm 2009)

Abstract

We experimentally demonstrate a two-way stable transmission of polarization encoded qubits over 23 km of spooled dispersion-shifted fiber with active polarization control in both directions, while simultaneously exchanging classical data. Two classical reference channels (one containing a telecom 10 Gb/s data stream), wavelength-multiplexed with the quantum signal, are used as feedback. The feasibility of quantum communication is demonstrated in the two opposite directions over 6 hours of continuous operation, as well as a classical error rate better than 1.0 x 10− 9.
