Quantum Computation and Quantum Communication with Entangled Photons
Anton Zeilinger · International Conference on Quantum Information · 2007
Entanglement is a fundamental resource both in long-distance quantum communication and in quantum computation. Because of its obvious indispensability in quantum teleportation, entanglement is crucial for quantum repeaters. Recently [1], we were able to synchronize two completely independent sources of entangled photons such that entanglement swapping became possible with independent lasers with high fidelity. In a future experiment, such lasers can be separated by kilometer distances.
