SUMMARY:Quantum money from Brandt operators (Shahed Sharif\, CSU San Marcos)
DESCRIPTION:Public key quantum money is a replacement for paper money which has cryptographic guarantees against counterfeiting. We propose a new idea for public key quantum money. In the abstract sense\, our bills are encoded as a joint eigenstate of a fixed system of commuting unitary operators. We show that the proposal is secure against black box attacks. In order to instantiate this protocol\, one needs to find a cryptographically complicated system of computable\, commuting\, unitary operators. To fill this need\, we propose using Brandt operators\, which have a beautiful tripartite formulation. No prior knowledge of quantum computers is necessary for this talk! This is joint work with Daniel Kane and Alice Silverberg.
