A New Monogamy-of-Entanglement Game for Coset States and Its Applications to Copy-Protection, Unclonable Encryption, and Tokenized Signatures
By leveraging the no-cloning principle of quantum mechanics, unclonable cryptography enables us to achieve novel cryptographic protocols that are otherwise impossible classically. Two most notable examples of unclonable cryptography are quantum copy-protection and unclonable encryption. Most known constructions rely on...
