Device bring-up and measurement infrastructure
Take quantum dot devices from the lab bench to operational readiness. Perform wire bonding, device packaging, and chip mounting for cryogenic testing, and design custom printed circuit boards for signal routing and filtering. Build and maintain cryogenic measurement setups including dilution refrigerators, fridge wiring, and line testing. Specify, install, and test low-noise amplifiers, DC lines, filters, bias tees, and microwave components, and develop robust procedures for cooldowns and thermal cycling.
Device tuning and characterization
Take devices from cooldown to working spin qubits. Run transport, radio-frequency reflectometry, and charge sensing measurements to identify quantum dot formation, tune gate voltages, and extract stability diagrams. Know whether the limit you are hitting is charge noise, tunnel coupling, or the readout chain.
Calibration automation
Encode expert tuning into software the platform runs on its own. Turn gate voltage tuning, stability diagram interpretation, and qubit calibration into routines that recover without a physicist in the room. Close the loop with the software and machine learning teams.
System performance and control stack
Keep systems stable and online. Diagnose charge rearrangement, drift between cooldowns, and fidelity degradation, and define the monitoring and recovery a spin qubit system needs to run unattended. Lead setup and scaling of the experimental lab environment, from defining requirements to speccing measurement equipment. Write or adapt control software for waveform generators, digital to analog converters, and lock-in amplifiers.
Collaboration and system integration
Work closely with physicists, machine learning engineers, and backend developers to integrate hardware, software, and data pipelines into a unified quantum control stack. Provide feedback on usability, stability, and performance from a hardware and systems perspective.
