ABSTRACT: We propose and demonstrate an optical implementation of a quantum key
distribution protocol, which uses three-non-orthogonal states and six states in
total. The proposed scheme improves the protocol that is proposed by Phoenix,
Barnett and Chefles [J. Mod. Opt. 47, 507 (2000)]. An additional feature, which
we introduce in our scheme, is that we add another detection set; where each
detection set has three non-orthogonal states. The inclusion of an additional
detection set leads to improved symmetry, increased eavesdropper detection and
higher security margin for our protocol.
