What this work contributes
Observes photon production and quantum correlations from rapidly modulated electrical boundary conditions in a superconducting circuit. It establishes a laboratory route for studying time-dependent boundaries.
Where the evidence stops
External modulation supplies energy. Emitted radiation carries momentum; the experiment is neither free-energy extraction nor a demonstration of reactionless vehicle thrust.
