Summary
High quality factor cavities can be powerful control elements for ensembles of spins, enabling unitary control as well as on demand cooling. They can also be used to couple two otherwise non-interacting ensembles. The goal of the project is to explore the physics and engineering of such systems both theoretically and experimentally. The laboratory contains a uniquely configured dilution refrigerator that has two volumes at the base temperature: one in a magnetic field and one in near zero magnetic field. This allows superconducting electronics to be used as control and measurement systems in conjunction with spin ensembles located in magnetic fields of up to 1 Tesla.

Coherent magnon generation, magnon condensation, and quantum spin liquids via spin pumping in 2D magnets
Summary Developing hybrid quantum systems is essential to harnessing the complementary advantages of different quantum technology platforms. This necessitates the successful transfer of quantum information between platforms, which can be achieved, e.g., by harnessing magnons, or spin wave excitations, in magnetic materials. Decoherence due to uncontrolled coupling of qubits to the environment remains a fundamental […]

Plasmon Control of Quantum States in Semiconductor Nanocrystals
Summary Thanks to the light-induced collective oscillations of free charges at the boundary between a conducting material and a dielectric, known as surface plasmon resonance, metallic nanostructures can exhibit strong light absorption and scattering. The sensitivity of these resonances to the local environment and shape of the metallic structures allows them to be used, […]

Quantum Computational Resources in the Presence of Symmetry
Summary Fault-tolerance is essential to the performance of quantum technologies, but known schemes are extremely resource intensive. Thus, improving existing schemes or inventing new schemes is of central importance. This joint project is based on the realization that fault-tolerance schemes make use of symmetries in fundamental ways, and that studying the problem of fault tolerance […]
