The uncontrolled interaction of a quantum system with its environment is detrimental for
quantum coherence. For quantum bits in the solid state, decoherence from thermal …

Coupled microwave photon-magnon hybrid systems offer promising applications by

We propose an experimentally realizable nonreciprocal magnonic device at the single-
magnon level by exploiting magnon blockade in a magnon-based hybrid system. The …

Cavity magnonics deals with the interaction of magnons—elementary excitations in
