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 ...
