Abstract: Secure delegated quantum computing allows a computationally weak client to outsource an arbitrary quantum computation to an untrusted quantum server in a privacy-preserving manner. One of the promising candidates to achieve classical delegation of quantum computation is classical-client remote state preparation, where a client remotely prepares a quantum state using a classical channel. In this talk, I will present some recent (impossibility and possibility) results concerning the security of remote state preparation and its application - universal blind quantum computing - using the constructive cryptography framework and game-based model.
