【Abstract】Quantum money allows banks to cast quantum money states that can be verified later and cannot be forged. Usually, the transmission of quantum states between banks and user needs to be involved. It is difficult to ensure the safe transmission of quantum states, which will lead to the loss and reconstruction of quantum money. In this paper, we make and store quantum states by the bank, and then the bank adds its own signature, which is public and verifiable by anyone. After the user adds his signature, the quantum currency is considered to be effective. We propose a trading application based on quantum money. We combine quantum money with blockchain to increase the security of quantum money. In addition, the analysis results show that our protocol is secure against some attacks.
