Classical Fully Homomorphic Encryption for Quantum Circuits: Difference between revisions

The example protocol [https://arxiv.org/abs/1708.02130 Mahadev (2017)] achieves the functionality of [[Secure Delegated Quantum Computation]] by a method which involves fully [[Secure Delegated Quantum Computation#Functionality Description|classical offline]] and no [[Secure Delegated Quantum Computation#Functionality Description|quantum communication]]. It uses only classical [[Supplementary Information#Quantum Cryptography Techniques#Quantum Capable Homomorphic Encryption|Homomorphic Encryption]] (HE) to evaluate quantum circuits 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 (any quantum gate) for required computation. Quantum offline communication would be required if Client’s input and output is quantum.</br>
