Shor and Preskill's and Mayers's security proof for the BB84 quantum key distribution protocol

  • D. Mayers

Abstract:

We review two security proofs for the BB84 quantum key distribution protocol: Mayers's security proof and the more recent proof of Shor and Preskill. We focus on the basic principles and the intuition in Mayers's proof instead of technical details. We present a variation on Shor's and Preskill's proof which is convenient for purpose of comparison. We explain the connection between these two proofs.
