Novel microwave isolator points the way to new radio cameras and quantum computers

Researchers at the National Astronomical Observatory of Japan (NAOJ) have invented a novel microwave isolator and have demonstrated, for the first time, its basic principle that enables small isolators; essential for future quantum computers. This isolator consists of two frequency mixers, which are widely used in receivers for radio telescopes, and paves the way for the development of large-scale multi-pixel radio cameras as well. The paper is published in the journal IEEE Microwave and Wireles...
