A compact microwave-photon detector built from a semiconductor double quantum dot and a superconducting cavity could sharpen ...

Detecting a single particle of light is hard; detecting a single microwave photon is even harder. Microwave photons, the tiny ...

Single-photon detection is a requisite technique in quantum-optics experiments in both the optical and the microwave domains. However, the energy of microwave quanta are four to five orders of ...

A highly sensitive detection technology has been developed that can detect microwaves down to 1 attowatt (aW, one quintillionth of a watt), the theoretical limit of detection. This breakthrough is ...

Physicists have discovered a way to use one of the information technology industry's mainstay materials -- gallium arsenide semiconductors -- as an ultrasensitive microwave detector that could be ...

A research team led by Pasquale Scarlino at EPFL has built a small, tunable detector capable of sensing individual microwave ...
