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.

Cryo-CMOS to Control and Operate 2D Fault-Tolerant Qubit Network
Summary Large-scale, fault-tolerant quantum computation requires precise and stable control of individual qubits. This project will use complementary metal-oxide-semiconductor (CMOS) technology to provide a cost-effective scalable platform for reliable and high-density control infrastructure for silicon spin qubits. We will use sub-micron CMOS technology to address device and circuit-level challenges and explore the integration of […]

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, […]
