Quantum Copy Protection and Position Verification
Quantum money is like one basis stone that we need to build copy protection upon, but it's not enough. We need something more. But if we cannot even get quantum money from well-funded assumptions, then there's probably no hope for us to get copy protection from well- funded assumptions. In some of these position verification protocols, people would do similar things as in just do the conjugate coding thing. The challenge is to recover the underlying classical secret encoded by the random basis. And I wouldn't say this is relied on this relies on quantum money because I think this basically all goes back to the non-cloning principle and going back to the properties of this conjugate
