Entanglement-inspired frequency-agile rangefinding

Nature Communications, Published online: 24 January 2026; doi:10.1038/s41467-026-68589-9

Quantum range finding struggles in bright background and at long distance. Here, the authors demonstrate a quantum-inspired, energy-time correlated classical rangefinder. It preserves quantum noise suppression, works at low power, and enables robust daylight remote ranging in real-world environments
