A quantum identification scheme based on polarization modulation
Guangqiang He, Zeng Gui-Hua · Chinese Physics · 2005
A quantum identification scheme including registration and identification phases is proposed. The users' passwords are transmitted by qubit string and recorded as a set of quantum operators. The security of the proposed scheme is guaranteed by the no-cloning theorem. Based on photon polarization modulation, an experimental approach is also designed to implement our proposed scheme.
