Abstract
Secure delegated quantum computing is a two-party cryptographic primitive, where a computationally weak client wishes to delegate an arbitrary quantum computation to an untrusted quantum server in a privacy-preserving manner. Communication via quantum channels is typically assumed such that the client can establish the necessary correlations with the server to securely perform the given task. This has the downside that all these protocols cannot be put to work for the average user unless a reliable quantum network is deployed.
Therefore the question becomes relevant whether it is possible to rely solely on classical channels between client and server and yet benefit from its quantum capabilities while retaining privacy. Classical-client remote state preparation (
