| Abstract: | An efficient quantum key distribution (QKD) protocol with orthogonal
product states in the 3 \otimes 3 Hilbert space is presented. The
sender, Alice, disorders the orthogonal product state sequence and
sends it to Bob. After Alice has published the matching information
of the particle sequence, Bob recovers the correct correspondences
and makes an orthogonal measurement on the orthogonal product states
to obtain the information sent by Alice. Finally, security analysis
is also made. |
