From Photonic Quantum Cloud Computing to Interactive Proofs
summary
Photonic experiments implement a blind, measurement-based delegated computation using an optical cluster state built from spontaneous parametric downconversion with four photons where the client encodes two blind qubits; verification uses trap qubits and records 91% trap success for correctness despite imperfect entanglement. The same platform runs small boson-sampling tests with three photons in five modes, maps output distributions versus photon distinguishability, and identifies the bottleneck as nondeterministic multi-photon sources rather than detectors or interferometers.
