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 ...

Detection using today’s microwave sensors has some advantages. Unlike traditional passive infrared motion sensors, most microwave sensors can distinguish between moving and static objects, and objects ...

Your garden variety motion detector uses IR, but these days, there are fancier technologies for achieving similar goals. If so desired, you can source yourself a microwave-based presence sensor ...

Spintronics exploits the intrinsic angular momentum of electrons—their spin—in addition to charge to create devices with novel functionalities. Key building blocks include magnetic tunnel junctions, ...
