Ultrafast long-distance quantum communication with linear optics — •Fabian Ewert, Marcel Bergmann, 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 based on quantum parity encoded qubits and linear optics. Provided individual qubits, as well as two-qubit entangled Bell states, can be prepared for this encoding, scalable quantum communication is possible (with rates independent of the total distance), while all the remaining operations after state preparation can be performed with experimentally feasible, static linear optics.
