Extremely simple unconditionally secure quantum bit commitment [PDF]
Guang Ping HeWe propose a quantum bit commitment (QBC) protocol based on the Mach-Zehnder interferometer, which requires one single photon only. The simple structure of the protocol makes it easy to verify that the cheating strategy in the Mayers-Lo-Chau no-go theorem of QBC can be evaded.View original: http://arxiv.org/abs/1212.4962
