On the (Im)plausibility of Public-Key Quantum Money from Collision-Resistant Hash Functions. (arXiv:2301.09236v1 [quant-ph])
cs.CR updates on arXiv.org arxiv.org
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.
These difficulties call for a deeper and systematic study of the structure of
public-key quantum money schemes and the assumptions they can be …
