Abstract
A secure quantum identification system combining a classical identification procedure and quantum key distribu- tion is proposed. Each identification sequence is always used just once and new sequences are "refuelled" from a shared provably secret key transferred through the quantum channel. Two identification protocols are devised. The first protocol can be applied when legitimate users have an unjammable public channel at their disposal. The deception probability is derived for the case of a noisy quantum channel. The second protocol employs uncondi- tionally secure authentication of information sent over the public channel, and thus it can be applied even in the case when an adversary is allowed to modify public communications. An experimental realization of a quantum identification system is described. PACS 03.67DKeywords
