Classical Fully Homomorphic Encryption for Quantum Circuits: Difference between revisions

Delegated Computation is the task of assigning quantum computation to an untrusted device while maintaining privacy of the computation. It can be done via classical online/offline and quantum online/offline communication. Following description deals with a method which involves fully classical offline and no quantum communication, which uses only classical Homomorphic Encryption (FHE) to evaluate quantum circuits homomorphically for classical input/input. It allows a fully classical Client to hide her data such that Server can carry out any arbitrary quantum computation on the encrypted data without having any knowledge about Client’s inputs. It hides the output and input of the computation while Server is allowed to choose the unitary operation for required computation. Quantum offline communication would be required if Client’s input and output is quantum.
