Nonreciprocal devices such as circulators or isolators are essential devices in signal processing.
quantum technologies, they serve to protect sensitive quantum systems from
excess noise. Conventionally, they rely on on the Faraday effect in ferrite
materials and require large magnetic fields. There is large interest in
magnetic-field-free alternatives integrable on superconducting chips. I will
present recent advances to make such devices with optomechanics, discuss the
underlying mechanism for directionality, and show how it is generalised to
arbitrary systems, especially fermionic ones.
