Abstract: Recently, Chau introduced an experimentally feasible qudit-based quantum-key-distribution (QKD) scheme. In that scheme, one bit of information is phase encoded in the prepared state in a $2^n$-dimensional Hilbert space in the form $(|i\rangle\pm|j\rangle)/\sqrt{2}$ with $n\ge… read more here.

Abstract: We propose a scheme to generate polarized hybrid entanglement in the form of |H 〉|α〉 + |V 〉|−α〉 by interference between a superposition of coherent states and a polarization entangled photon pair. In the scheme… read more here.
