Copy-protection allows a software distributor to encode a program in such a
way that it can be evaluated on any input, yet it cannot be "pirated" - a
notion that is impossible to achieve in a classical setting. Aaronson (CCC
2009) initiated the formal study of quantum copy-protection schemes, and
speculated that quantum cryptography could offer a solution to the problem
thanks to the quantum no-cloning theorem. In this work, we introduce a quantum
copy-protection scheme for a large class …
