For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the ...

To detect radio signals using a gas, researchers first have to perform a quantum magic trick. They use a sequence of lasers ...

The possibility to exactly solve quantum mechanical problems such as the hydrogen atom is based on the existence of symmetries from which constants of motion arise, reducing the degrees of freedom and ...
