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 classical CMOS and quantum computing components. Since spin qubit control and measurement requires CMOS to operate at milli-Kelvin temperatures – far below the normal operating range of classical electronic devices – we will develop and calibrate compact models for MOSFETs at cryogenic temperatures, considering electrical, thermal and noise behaviors. These models will be used for cryo-CMOS design for spin qubit control operations, data readout, and communication, in a compact and scalable way at the node level. We hope to eventually implement integrated, readily scalable spin qubit control systems by bridging the classic CMOS and quantum platforms.
Materials for Majorana-based Topological Qubits
Summary Topological qubits offer a novel pathway to scalable quantum computing by simultaneously allowing for ease of coupling between qubits and strong decoupling of qubits from noise and dissipation. The most promising direction explores the topologically induced protection of theoretically predicted exotic quasiparticles, the so-called Majorana Zero Modes or MZMs. To-date MZMs, which follow […]

Applications of Neutron Interferometry and Structured Neutron Beams
Summary Neutrons are a powerful probe of matter and physics due to their Angstrom size wavelengths, electric neutrality and relatively large mass. In this project, we develop quantum sensors that exploit these attributes to increases the precision of measurements of fundamental forces and materials structure. With David Cory, Alexander Cronin of the University of Arizona, […]
