"generating encryption/ decryption keys independently eliminates operational burden of tracking sequential, gate-by-gate key updates during computation... conceals target operations within their Pauli equivalence class, preserving full quantum functionality... verification measures randomly sampled Pauli observables, flag malicious/ noisy server deviations with low computational overhead... scalable, tested on IBM superconducting quantum processors... secure cloud-based quantum computing"
