Army researchers detect broadest frequencies ever with quantum receiver A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for Soldier communications, spectrum awareness and electronic warfare. Army researchers built the quantum sensor, which can sample the radio-frequency spectrum—from zero frequency up to 20 GHz—and detect AM […]
Rydberg Atoms Ryding a Train of Photons
Rydberg Atoms Ryding a Train of Photons Scientists see train of photons in a new light In brief… + Flashlight beams don’t clash together like lightsabers because individual units of light—photons—generally don’t interact with each other. Two beams don’t even flicker when they cross paths.+ But by using matter as an intermediary, scientists have unlocked […]
