Using Rydberg Atoms & Quantum Sensing, U.S. Defense Researchers Detect Broadest Frequencies Ever

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 […]

U.S. Army to Leverage Quantum Sensing’s “Nonintuitive Properties”

U.S. Army to Leverage Quantum Sensing’s “Nonintuitive Properties.”  Entanglement, wave-particle duality, superposition:  These properties are key to quantum sensing.  And the U.S. Army intends to leverage these properties for national defense applications. “Quantum sensing uses some nonintuitive properties of nature to measure things like time, magnetic fields, gravity, or acceleration,” explains Paul Kunz, a scientist […]
