Quantum cryptography provides an ensemble of protocols, such as quantum key distribution [1-3], quantum random number generation [4], closed group digital signatures [5], long-term secure data storage [6] and multi-party secure computation [7], which are robust against future algorithmic and computational advances, including the emergence of quantum computers. This is because its security is information-theoretic, i.e., it can be proven based only on models of the local devices operated by legitimate users and does not require any assumptions on the resources available to an adversary
