The Solid Quantum Systems (SQS) group develops semiconductor quantum devices and hybrid quantum systems for scalable quantum computing. Our research focuses on quantum-dot spin qubits in materials including silicon, germanium, and two-dimensional systems, with particular interest in high-fidelity multi-qubit operation and readout, and the physical mechanisms that limit device performance.

A central goal of the group is to understand how semiconductor qubits can be scaled from a few well-controlled quantum dots to larger and more connected systems. We develop quantum-dot arrays to study qubit uniformity, control, noise, and interactions in increasingly complex devices, while exploring new materials and device architectures that can simplify fabrication and improve scalability.

We also investigate hybrid approaches that combine semiconductor qubits with superconducting microwave circuits. Such systems provide new possibilities for sensitive readout, long-range coupling, and coherent connections between spatially separated qubits or modules.

More broadly, our work aims to connect advances in semiconductor materials, nanofabrication, quantum control, and circuit quantum electrodynamics to develop practical architectures for future quantum processors.
