Cheat sensitive quantum bit commitment via pre- and post-selected quantum states
Cheat sensitive quantum bit commitment is a most important and realizable quantum bit commitment (QBC) protocol. By taking advantage of quantum mechanism, it can achieve higher security than classical bit commitment. In this paper, we propose a QBC schemes based on pre- and post-selected quantum states. The analysis indicates that both of the two participants cheat strategies will be detected with non-zero probability. And the protocol can be implemented with todays technology as a long-term quantum memory is not needed.
