Engineered atomic interactions help microwave sensor capture three times as much information

Researchers from the Faculty of Physics at the University of Warsaw (UW) and the Center for Optical Quantum Technologies at the University of Warsaw's Center for New Technologies (CeNT UW) have developed a method for ultrasensitive microwave sensing. Using cold, strongly interacting Rydberg atoms as a microwave detector, the researchers observed that carefully engineered interactions between the atoms make the atomic state resistant to loss.
