Prepare-and-Send Universal Blind Quantum Computation: Difference between revisions

The [https://arxiv.org/abs/0807.4154 example protocol] achieves the functionality of [[Secure Client- Server Delegated Computation|Delegated Computation]] is the task of assigning quantum computation to an untrusted device while maintaining privacy of the computation. It can be done via [[Secure Client- Server Delegated Computation#Protocols|classical online/offline]] and [[Secure Client- Server Delegated Computation#Protocols|quantum online/offline]] communication. Following description deals with a method which involves quantum offline and classical online communication, called Blind Quantum Computation. It comes with the properties of correctness i.e. if both parties follow the protocol the final outcome is correct, blindness i.e. the Client to have Server carry out a quantum computation for her (Client) such that the Client’s inputs, outputs and circuit used for computation remain perfectly private from the Server and Universality i.e. the following protocol can implement any quantum computation.</br> </br>
