Abstract
Secure, semi-classical authentication schemes are presented. An authentication token is generated by applying a pre-determined measurement to a plurality of random quantum states to obtain a sequence of classical measurement outcomes. The token is validated by receiving the classical measurement outcomes and verifying whether the sequence corresponds to a statistically plausible result for the pre-determined measurement of the plurality of quantum states.
