One-Kilometer Free-Space Quantum Entanglement Communication Test
Sector: Telecommunications • Location: Delhi, India
Source: The Quantum Insider
India demonstrated free-space quantum secure communication using entanglement over a one-kilometer link at IIT Delhi. The experiment achieved a secure key rate of approximately 240 bits per second with a quantum bit error rate below 7%, using a photonic system developed under a DRDO-supported project. This technology enables long-distance secure communication without fiber-optic cables and support
