Background: "Quantum money is a proposed design of bank notes making them impossible to forge, by using quantum physics. The idea influenced the development of quantum key distribution protocols used in quantum cryptography. The idea was put forward in about 1970 by Stephen Wiesner, a graduate student at Columbia University, though it was rejected by a number of scientific journals, meaning that it remained unpublished until 1983." https://en.m.wikipedia.org/wiki/Quantum_money https://en.m.wikipedia.org/wiki/Quantum_money
