Quantum Money is a quantum cryptographic scheme that was first introduced by Wiesner [Wie83] in 1983. Informally, a quantum coin is a unique object that is created by a Trusted Third Party (TTP). Then, it is circulated among untrusted clients (Transferrability property). Each client should be able to verify it and confirm that it is authentic if it has been circulated according to the prescribed rules. On the other hand, an adversary must fail in counterfeiting it with overwhelmingly high probability (Unforgeability property). The quantum money schemes can be classified in two categories: Public Quantum Money and Private Quantum Money.
