 == Functionality Description==
-Delegated Computation is the task of assigning computation on hidden data to a powerful untrusted party (a device) by a weak (in terms of computational powers) party while maintaining privacy of hidden data from the powerful party. Protocols under this functionality are commonly called Client (weak party)-Server (powerful party) protocols. Delegated Quantum Computation (DQC) protocols involve partially/fully classical Client delegating a quantum computation to fully powerful single/multiple quantum Server/Servers. All DQC protocols involve three main stages, Preparation Stage, Computation Stage and Output Correction Stage. The roles of Client and Server in the different stages may differ according to the type of communication used. It can be performed via classical and quantum communication. If it is carried out only during Preparation and Correction stage, it is called offline communication else if the communication is carried out during the computation stage, it is online communication. If the outcome can be verified by the Client it is a verifiable delegated quantum computation protocol. Hence, based on the above requirements, DQC protocols can be classified as follows.
