TY - CHAP ID - 623481 AU - Bouda, Jan PY - 2005 TI - Exact and approximate encryption of quantum information VL - Vol. 17 PB - IOP Press, 2008 CY - Amsterdam, Netherlands SN - 9781586038564 KW - approximative quantum encryption N2 - In this paper, we address properties of the private quantum channel (PQC), namely a security weakness occurring when at least two copies of the ciphertext are available. We discuss possible definitions of the known-plaintext, known-ciphertext and chosen-plaintext attack. We examine the ability of a PQC to randomize correlations and, finally, we show that specific PQCs encrypting a given set of plaintexts can achieve the approximate encryption of a larger set of plaintexts.
