Wiesner's quantum money scheme was first published in 1983. The idea influenced the development of quantum key distribution protocols used in quantum cryptography. The first proposal for a quantum money scheme is due to Stephen Wiesner circa 1970, though it remained unpublished until 1983.
Utilizing this idea, quantum money schemes produce banknotes which are impossible to forge by including quantum systems in their design. The key idea is that arbitrary quantum states cannot, in general, be perfectly copied (a fact known as the no-cloning theorem). A quantum money scheme is a quantum cryptographic protocol to create and validate banknotes which are impossible to forge.
