Shor and Preskill give a simpler security proof for BB84

Mar 1, 2000

Peter Shor and John Preskill prove the security of the BB84 key-distribution protocol by connecting it to entanglement purification and quantum error-correcting codes. The proof concerns the protocol under its theoretical assumptions.

Why it matters

A tractable security proof strengthens the foundations of quantum key distribution while leaving real devices' departures from the model to be addressed.
