A Quantum Photonic Processor Worked in Orbit
A nanosatellite generated, manipulated and detected non-classical light in a programmable six-mode circuit.
Summary
A nanosatellite generated, manipulated and detected non-classical light in a programmable six-mode circuit.
Researchers report operating a programmable quantum photonic platform aboard a nanosatellite. The payload processed two photons in a six-mode integrated circuit, programmed distinct optical transformations and tuned the photons into indistinguishability; the observed two-photon interference establishes onboard generation, manipulation and detection of non-classical light. The demonstration moves quantum states of light from orbital communication experiments toward computation, but it is not a claim of general-purpose quantum advantage or a production Earth-observation system.
Why it matters
