Bidirectional quantum secret sharing and secret splitting with polarized single photons
Abstract
In this Letter, we present quantum secret sharing and secret splitting protocols with single photons running forth and back between the participating parties. The protocol has a high intrinsic efficiency, namely all photons except those chosen for eavesdropping check could be used for sharing secret. The participants need not to announce the measuring bases at most of the time and this reduces the classical information exchanged largely.
