Ultrafast Fault-Tolerant Long-Distance Quantum Communication with Static Linear Optics — •Fabian Ewert and Peter van Loock — Institut für Physik, Johannes Gutenberg-Universität, Staudingerweg 7, D-55128 Mainz

We present an all-optical, ultrafast scheme for long-distance quantum communication that can handle both photon losses and various depolarizing errors, e.g., caused by faulty detectors and resource states. The scheme is based on quantum parity encoded qubits and static linear optics. Nonlinear effects are only required for the generation of encoded qubits and Bell states where we propose to use coherent photon conversion which also allows for a static setup and, in principle, an on-chip integration.
