“Universal blind measurement-based quantum computations”
Abstract: We consider a scenario in which a client (Alice) with limited computational power wishes to perform universal quantum computations via a server (Bob) without revealing their underlying computation. In this talk we discuss an interactive client-server protocol due to Broadbent, et al. [1]. This protocol requires no computational assumptions and has perfect privacy, i.e., the server learns nothing about the client’s inputs, outputs, or desired computation. Furthermore, the protocol is formulated using measurement-based quantum computing (MBQC), which is an alternative universal model of quantum computation driven by single-qubit measurements on an entangled resource state. For the purposes of private quantum computations, a new universal resource for MBQC, called the brickwork state, is identified and universality is established. Time permitting, we also discuss variations of the original protocol with quantum inputs and quantum outputs, as well as a protocol for the client to authenticate the results they receive from the server.
