Platform
Diamond, optical fibres, magnetic films and nanomechanical structures.

03 · Hybrid Quantum Systems
Collective excitations can act as a tunable bridge between quantum systems that otherwise do not naturally communicate.

The question
Magnons carry collective spin motion; phonons carry motion through a crystal. We study both as measurable physical systems and as possible links between microwave, optical and solid-state quantum platforms.
How we approach it
Diamond, optical fibres, magnetic films and nanomechanical structures.
Brillouin spectroscopy, heterodyne detection, photon counting and local magnetic imaging.
Coherent transport, non-equilibrium statistics and microwave-to-optical transduction.
Current directions
These project areas evolve as experiments and collaborations develop.
Controlling high-frequency sound in low-loss structures for distributed quantum technologies.
Resolving interference, propagation and nonlinear dynamics with diamond magnetic microscopy.
Combining heterodyne and photon-counting measurements to access phase and statistics together.
