  Article: Improving the Control Strategy in two-way deterministic cryptographic protocols

  Anita Eusebi, Stefano Mancini
  [show abstract] [hide abstract]
  ABSTRACT: We introduce a new control strategy on a two-way deterministic cryptographic scheme, which relies on a suitable unitary transformation rather than quantum measurement. The study is developed for d-ary alphabets and the particular choice of the transformation works when d is an odd prime power. It leads to an improvement of the protocol security, which we prove to increase with the alphabet order d.

  Article: Deterministic Quantum Distribution of a d-ary key

  Anita Eusebi, Stefano Mancini
  [show abstract] [hide abstract]
  ABSTRACT: We present an extension to a d-ary alphabet of a recently proposed deterministic quantum key distribution protocol. It relies on the use of mutually unbiased bases in prime power dimension d, for which we provide an explicit expression. Then, by considering a powerful individual attack, we show that the security of the protocol is maximal for d=3. Comment: 12 pages, 2 figures
