Advances in quantum computing and telecommunications stimulate the search for classical
systems allowing partial implementation of a similar functionality under less stringent …

In general, a magnon does not interact directly with an atom. Here we present a scheme to
generate coherent coupling between two magnons and a superconducting artificial atom via …

We analyze quantum computation using quantum information stored on two component
Bose-Einstein condensates (BECs). We construct a general framework for quantum …

Under suitable experimental conditions, collective spin-wave excitations, magnons, form a
Bose–Einstein condensate (BEC), where the spins precess with a globally coherent phase …

Over the past decade, significant progress has been achieved to create Bose-Einstein
condensates (BECs) of magnetic excitations, ie, magnons, at room temperature, which is a …

We propose to directly and quantum-coherently couple a superconducting transmon qubit to
magnons—the quanta of the collective spin excitations, in a nearby magnetic particle. The …

Combining different physical systems in hybrid quantum circuits opens up novel possibilities
for quantum technologies. In quantum magnonics, quanta of collective excitation modes in a …
