Abstract
We analyse the Bennett-Wiesner dense quantum coding scheme for non-maximally entangled carriers of information. Our generalization shows that the detection scheme proposed by Bennett and Wiesner is optimal even when the entanglement is not perfect. We comment on the optical realization of the scheme.Keywords
