Semi-Quantum Money

Understand

Quantum money allows a bank to mint quantum money states that can later be verified and cannot be forged.

• Usually, this requires a quantum communication infrastructure to transfer quantum states between the user and the bank.
• Gavinsky (CCC 2012) introduced the notion of classically verifiable quantum money, which allows verification through classical communication.
• In this work we introduce the notion of classical minting, and combine it with classical verification to introduce semi-quantum money.
