An online attack against Wiesner's quantum money
Andrew Lutomirski · arXiv (Cornell University) · 2010
Wiesner's quantum money [5] is a simple, information-theoretically secure quantum cryptographic protocol. In his protocol, a mint issues quantum bills and anyone can query the mint to authenticate a bill. If the mint returns bogus bills when it is asked to authenticate them, then the protocol can be broken in linear time.
