Secure Client- Server Delegated Computation: Difference between revisions

It involves a partially quantum Client perform quantum and classical communication throughout the protocol. The Client and Server then exchange classical messages during the computation phase. Universal Blind Quantum Computation (UBQC) is a protocol falling under this category. In this protocol Client hides his input, output and computation from the Server using [[Supplementary Information#Measurement Based Quantum Computation|MBQC]] by sending hidden quantum states to the Server. Such UBQC protocols can be realised by a [[Measurement Only Universal Blind Quantum Computation|Measurement Only UBQC]] protocol where the client measures some known quantum state prepared by server in a rotated basis to generate input states. Same as UBQC, VUBQC can also be realised by [[Measurement Only Verifiable Universal Blind Quantum Computation|Measurement Only VUBQC]] protocols.

It involves a fully classical Client exchanging classical messages with the server throughout. Protocols falling under this category are [[Q-Factory|Q-Factory]]. A verification of Q-Factory protocol is still an open question.
