Description
Quantum computers allow for a higher level of security in information exchange than their classical counterpart. As an example, by using the so-called blind quantum computing protocols, a client can delegate a complex quantum computation to a server in a completely secure way, without any leaks of information on the input, the output or the computation algorithm. In this work, we realize a blind quantum computing between a completely classical client and a single quantum server, where the classical client uses an ambiguity in the information flow in measurement-based quantum computing to hide the computation algorithm. Our demonstration represents a step toward real-life applications of blind quantum computing, where classical clients delegate computation tasks to a single photonic quantum server.
