We perform end-to-end development of superconducting quantum circuits, including design, simulation, nanofabrication, and cryogenic measurement of transmon and related qubits. We study how materials, processes, and circuit parameters impact coherence, control, and engineered interactions.

Qubit fundamentals and decoherence: We investigate microscopic sources of noise that limit performance at the few-qubit scale, including charge-parity dynamics, quasiparticle generation and mitigation, and other loss mechanisms that constrain coherence.

Hot-qubit technologies: Our team explores superconducting qubits designed for elevated-temperature operation (> 1 K), such as nitride-based platforms. This work examines new initialization, control, and readout strategies required for operation in warmer cryogenic environments.

Novel readout approaches: We develop advanced measurement techniques, including MIST-based methods and fluxonium readout schemes, to improve sensitivity, speed, and operational flexibility of superconducting circuits.

Quantum processors and scaling: We study pathways to scaling superconducting qubits through novel coupling architectures and interconnect strategies, with particular emphasis on understanding crosstalk and parasitic interactions in multi-qubit systems.
