    chemistry grand challenge nitrogen vacancy nv defect in diamond p defect in si phosphorus sensing silicon

    Summary

     

    There are small quantum systems over which we have very good control and which have long lifetimes. Examples include the phosphorous (P) defect in silicon (Si) and the nitrogen vacancy (NV) defect in diamond. With P defect in Si, we focus on improving our understanding of the hyperpolarization mechanism to better enable engineering of quantum systems that are highly and quickly polarizable with long coherence times. With the NV defect in diamond, we are developing control methods to suppress zero-field splitting, a miniaturized optics setup and a small package for the required microwave and control hardware. We also utilize the NV defect in diamond as a chemical sensing platform to enable sensing of a target molecule of choice. Advancements in these areas offer the potential to transform a host of technologies from gyroscopes to magnetometers.

    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 Dynamics of Cavity Interactions with Spin Ensembles

    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 […]

    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 […]
