What was discovered
Two-photon quantum interference effect: when two identical photons enter a beam splitter through different ports with perfect temporal overlap, they always exit together through the same output, with zero coincidence detections.
What it led to
- indistinguishable photon sources for quantum computing
- single-photon quality testing
- quantum cryptography protocols
- precision experimental quantum optics
