Deterministic and verifiable blind quantum computing with trapped ions

ORAL

Abstract

Delegating quantum computations to a server usually comes at the cost of waiving privacy and security. Blind quantum computing addresses this issue through interactive protocols.

In this experiment, we enable a client with limited resources to delegate algorithms to a trapped-ion quantum computer via a photonic link. Using the test-or-compute strategy, we perform verifiable blind single-qubit rotations in both the measurement-based model and the circuit model of quantum computing.

We discuss the impact of noisy hardware on the security and robustness of the computation. Our implementation does not depend on the computational model, is scalable without hardware modifications, and does not require post-selection due to the adaptive nature of the protocol.
