Symposium MQ01-Coherent and Correlated Magnetic Materials for Hybrid Quantum Interfaces

Increasing activity in quantum information systems (QIS) has highlighted the need to move beyond isolated systems with a single coherent quantum state to more complex quantum networks where this coherence is transduced between distinct elements and degrees of freedom (for example between optical and microwave photons used for quantum communication and quantum computation, respectively). The spin degree of freedom is a promising candidate for this transduction. For example, recent advances in measurements of coherent electronic spin dynamics, especially near room temperature, underlies fundamental advances in sensing, quantum information processing, and low-power (non-quantum) devices such as magnetic memory and spin logic. A wide variety of materials exhibit coherent electronic spin dynamics, and thus studies of these effects have cross-platform implications. For example, at the single spin level similar dynamics can occur in diamond color centers, chromophores, organic light emitting diodes, silicon quantum dots, and complex oxide heterostructures while correlated spin excitations (e.g. magnons) can dramatically enhance coupling to single spins, microwave photons, and optical scattering. Fundamental theories of spin transfer, spin pumping, photonic coupling, and intersystem crossings are now being applied across these materials and disciplinary boundaries of spin physics, spin chemistry, and quantum information.

In order to focus on the directions of most immediate interest the emphasis of the symposium will be on materials and devices in which these effects occur at room temperature, or where a pathway towards room temperature is feasible.
