Linear optical setups for active and passive quantum error correction in polarization encoded qubits
José Cláudio do Nascimento, Fábio Alencar Mendonça, Rubens Viana Ramos
In this work, we present active and passive linear optical setups for error correction in quantum communication systems that employ polarization of single-photon and mesoscopic coherent states. The proposed systems are analytically analysed and their applications in quantum communication systems are described. In particular, we show a security analysis of a QKD system employing the active error correction system when an eavesdropper uses the Fuchs–Peres–Brandt attack.
