Quantum repeaters offer a route to entanglement over long distances

Mar 20, 1998

Hans Briegel, Wolfgang Dür, Ignacio Cirac and Peter Zoller propose linking shorter entangled pairs and improving their quality in stages. The repeater scheme tackles the rapid buildup of errors when quantum information travels through noisy channels.

Why it matters

Repeaters provide a foundation for quantum networks that could connect distant processors without sending fragile quantum states through one long channel.
