Cryogenic wiring, RF reflectometry, measurement automation, and validation workflows for quantum-device infrastructure.
This project summarizes experimental infrastructure for semiconductor quantum-device measurements in a dilution refrigerator. The work centers on low-noise DC and RF lines, grounding, shielding, filtering, measurement automation, and system-level validation for millikelvin qubit experiments.
I designed and integrated RF lines and electronic components, including filters and breakout or hot-swap boxes, for low-noise cryogenic measurements. The workflow includes customization of an Oxford Instruments Triton dilution refrigerator, equipment-frame grounding, cable fabrication, soldering, and installation of RF components such as attenuators, directional couplers, and bias-tees.
A key part of the project was validating the measurement chain with a network analyzer by characterizing S-parameters and checking signal integrity. The work also included practical cryostat maintenance, including helium-line cleaning and disassembly tasks needed to keep the system reliable for long experiments.
