Tuning into Atomic Radio: Quantum Technique Unlocks Laser-Based Radio Reception
https://hackaday.com/2019/07/17/tuning-into-atomic-radio-quantum-technique-unlocks-laser-based-radio-reception/
The basic technology of radio hasn’t changed much since an Italian marquis first blasted telegraph messages across the Atlantic using a souped-up spark plug and a couple of coils of wire. Then as now, receiving radio waves relies on antennas of just the right shape and size to use the …read more (https://hackaday.com/2019/07/17/tuning-into-atomic-radio-quantum-technique-unlocks-laser-based-radio-reception/)
