Quantum Magnonics

Magnetism has long been studied for classical applications in low-loss logic and memory, and recently, its advantages in developing quantum technologies have been recognised. Magnets support low-loss excitations called magnons across a broad frequency range from GHz to THz, and with high scalability spanning nanometers to millimetres. Additionally, they couple to a variety of other quantum systems, including spin centres and superconducting qubits. Some applications where magnons may thrive are nanoscale bosonic qubits, quantum interconnects, and frequency transduction.

However, realising these promises requires addressing challenges across multiple research frontiers. From a theoretical perspective, we need to model the quantum dynamics of magnons under different forms of excitations, and develop protocols for magnon manipulation. Experimentally, advancements in device fabrication and measurement techniques are needed.

This workshop brings together a diverse set of expertise that is collectively needed to advance the fundamental understanding and technological capability of magnons in the quantum domain. The program comprises four themes: (1) hybrid quantum systems: coupling magnons to other quantum platforms for their manipulation and readout; (2) cavity magnonics: exploiting the extremely strong magnon-microwave coupling that makes this the most promising platform for magnon control; (3) nonlinear magnonics: essential for generating genuine quantum effects beyond classical linear dynamics; and (4) magnetic materials: development of materials needed for future quantum magnonic devices.

The workshop will be highly international, featuring invited speakers from 11 countries working at the forefront of quantum magnonics. Non-speaker participants are encouraged to present their research through posters.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
