Verifiable Blind Quantum Computing with Trapped Ions and Single Photons

Wed, 10 Apr 2024 00:00:00 +0000

We report the first hybrid matter-photon implementation of verifiable blind quantum computing. We use a trapped-ion quantum server and a client-side photonic detection system networked via a fiber-optic quantum link. The availability of memory qubits and deterministic entangling gates enables interactive protocols without postselection—key requirements for any scalable blind server, which previous realizations could not provide. We quantify the privacy at ≲ 0.03 leaked classical bits per qubit. This experiment demonstrates a path to fully verified quantum computing in the cloud.

We present the first hybrid matter-photon implementation of verifiable blind quantum computing. We use a trapped-ion quantum server and a client-side photonic detection system connected by a fibre-optic quantum network link. The availability of memory qubits and deterministic quantum logic enables interactive protocols without post-selection - a requirement for any scalable blind quantum cloud server which previous realisations could not provide. Our apparatus supports guaranteed privacy with <0.001 leaked bits per qubit and shows a clear path to fully verified quantum computing in the cloud.
