Detecting a single particle of light is hard; detecting a single microwave photon is even harder. Microwave photons, the tiny packets of electromagnetic radiation used in current technologies like ...

A compact microwave-photon detector built from a semiconductor double quantum dot and a superconducting cavity could sharpen qubit readout in quantum computers, according to a new preprint from ...

Researchers have built a device that detects individual microwave photons with up to 70 percent efficiency, operating continuously and without complex reset steps. (Nanowerk News) Detecting a single ...

A research team led by Pasquale Scarlino at EPFL has built a small, tunable detector capable of sensing individual microwave photons and converting them into measurable electrical current. The device ...
