Abstract:
Blind quantum computing enables a client to delegate computations while hiding their data and even the underlying algorithm from the cloud server. Confidential information can be protected with information-theoretic security, and incorrect operation of the server or attempted attacks can be detected – a remarkable possibility that has no equivalent in classical computing.
In this seminar, we will discuss the measurement-based paradigm of (verifiable, blind) quantum computing, and present the first scalable experimental demonstration [1] of this concept, using a trapped-ion quantum server and a client-side photonic detection system networked via a fiber-optic quantum link. The availability of deterministic logic gates and a state-of-the-art quantum memory in the server [2] enables interactive protocols without post-selection - key requirements for any platform to provide scalable and secure quantum cloud computing.
