Quantum Communication and Quantum Computation with Entangled Photons - Anton Zeilinger

Quantum communication with entangled photons has advanced beyond the laboratory. Entangled photon links now exist over distances up to 8km in the city of Vienna. Such experiments have demonstrated successfully that quantum cryptography via satellites in Earth orbit is possible. Moreover, in quantum computation, probabilistic gates have been demonstrated, and recently the non-probabilistic comcept of a one-way quantum computer has been realized for 4 qubits in a cluster state.
