NIST Studies Use of Quantum Physics to Support Underground, Underwater & Indoor Comms

The National Institute of Standards and Technology has begun to experiment with “quantum radios” that might be able to support communications and mapping in environments where radios, global positioning systems and cellphones cannot operate reliably. NIST said Tuesday its researchers are studying very low frequency digitally-modulated magnetic signals that can penetrate building …
