Abstract:

Based on Heisenberg’s uncertainty principle and non-cloning principle in quantum mechanics, quantum money with quantum states as the carrier has certain advantages in anti-counterfeiting, anti-double-spending and anti-quantum computing. In this paper, according to the scenarios of bank, cheque issuer and receiver for cheque generation, issuance and verification, a quantum cheque protocol using Bell state is proposed, and its correctness, verifiability, unforgeability, non-repudiation and tamper-proof are analyzed. Compared with the existing quantum cheque schemes, this protocol reduces the requirement of quantum entanglement and improves the feasibility of implementation.

Key words: quantum cheque, quantum money, Bell state
