A nonreciprocal optomagnonic device that has dual properties of classical and quantum nonreciprocity is proposed by Hong‐Yu Liu, Rong‐Can Yang, and co‐workers in article number 2000196. The system consists of a magnon mode and a mechanical mode of the YIG sphere and a spinning microwave oscillator. Due to the Fizeau light‐dragging effect, the effective cavity frequency can be shifted by the direction of the input light, leading to a nonreciprocal magnon–phonon entangled state.
