ePrint Report: On the (Im)plausibility of Public-Key Quantum Money from Collision-Resistant Hash Functions

Prabhanjan Ananth, Zihan Hu, Henry Yuen

Public-key quantum money is a cryptographic proposal for using highly entangled quantum states as currency that is publicly verifiable yet resistant to counterfeiting due to the laws of physics. Despite significant interest, constructing provably-secure public-key quantum money schemes based on standard cryptographic assumptions has remained an elusive goal. Even proposing plausibly-secure candidate schemes has been a challenge.
