Uncloneable quantum money

Abstract

One of the earliest cryptographic applications of the quantum no-cloning theorem was to create quantum digital cash that could not be counterfeited. In this poster, we develop two notions of quantum money, namely quantum coins and quantum bills, which have many of the desirable properties of digital cash, such as non-counterfeitability and transferability. Quantum coins can be non-destructively verified but cannot be efficiently cloned in the black box model. Quantum bills have greater resistance to counterfeiting outside the black box model at the expense of anonymity.

Keywords: quantum coins, quantum cryptography, digital cash
