“Delegating Private Quantum Computations”
Abstract: In this talk, we present a protocol introduced by Broadbent [1] for delegating quantum computations on encrypted data. The protocol is intended for a client with limited quantum resources and enables a remote quantum server to execute a publicly known quantum circuit while the client’s sensitive input data remains perfectly encrypted via the quantum one-time pad. In our scheme, all Clifford group operations are performed non-interactively on the encrypted data, while non-Clifford gates requires only minimal interaction—specifically, the client prepares and sends a single random auxiliary qubit and exchanges a couple of classical bits with the server. We also discuss the security proof, which guarantees that even a malicious server deviating arbitrarily from the protocol cannot gain any information about the client’s data.
