In the last five years, a new field has emerged at the intersection between Condensed Matter and Quantum Optics, denominated “Quantum
Magnonics”. This field strives to control the elementary excitation of magnetic materials, denominated magnons, to the level of the single
quanta, and to interface them coherently to other elementary excitation such as photons or phonons. The recent developments in this field, with
proof of concept experiments such as a single-magnon detector, have opened the door for hybrid quantum systems based on magnetic materials.
This can allow us to explore magnetism in new ways and regimes, has the potential of unraveling quantum phenomena at unprecedented scales, and
could lead to breakthroughs for quantum technologies. A predominant role in these developments is played by cavity optomagnonic systems, where an
electromagnetic cavity, either in the optical or microwave regime, is used to enhance and control the interaction between photons and magnons. In this
talk, I will introduce the field of Quantum Magnonics with emphasis on Cavity Optomagnonics, and present some theoretical results from our group
which aim to push the boundaries of the current state of the art.
