The following Universal Blind Quantum Computation (UBQC) protocol uses the unique feature of [[Supplementary Information#Measurement Based Quantum Computation|Measurement Based Quantum Computation(MBQC)]] that separates the classical and quantum parts of a computation. Based on its counterpart Prepare and Send UBQC, this protocol requires Client to possess only a measurement device in order to perform blind quantum computation, hence the name 'Measurement Only UBQC'. The motivation behind this protocol lies in the fact that for several experimental setup like optical systems, measurement of a state is much easier than generation of a state. Presented below are two versions of the protocol. The first protocol needs only quantum communication throughout the protocol while second needs both quantum and classical throughout communication. These protocols are designed for classical input and output. It can be extended to quantum input/output by modifying the measurement angles of the Client according to Prepare and Send UBQC in order to hide her quantum output from the Server. Like all the other delegated quantum computing protocols, this protocol is also divided into two stages, Preparation and Computation.
