Quantum cryptography with classical communication: parallel remote state preparation for copy-protection, verification, and more. (arXiv:2201.13445v1 [quant-ph] CROSS LISTED)

Quantum mechanical effects have enabled the construction of cryptographic
primitives that are impossible classically. For example, quantum
copy-protection allows for a program to be encoded in a quantum state in such a
way that the program can be evaluated, but not copied. Many of these
cryptographic primitives are two-party protocols, where one party, Bob, has
full quantum computational capabilities, and the other party, Alice, is only
required to send random BB84 states to Bob. In this work, we show how …
