Superconducting and silicon-based qubits necessitate high-frequency electronics, typically operating in the 100 MHz to 10 GHz range, for both stimulation and measurement. These systems interface with cryogenic equipment to enable quantum experiments. This project centers on two critical components: (i) optimizing signal pathways between control electronics and quantum processors in collaboration with Maybell Quantum Industries, and (ii) establishing a dedicated RF probe station for precise measurements. Beyond addressing contemporary engineering challenges in quantum information, this project offers opportunities to contribute to and benefit from broader research initiatives within our group.

The team will be mentored by two PIs (one in Physics and one in EE). In addition, they will be part of meetings with Maybell Quantum to discuss the developments. They will also work with 3 PhD students (in Physics) and one MS student (in EE and QE) in the group whose research programs this project is aimed to benefit. The team will report their progress in a group meeting once every two weeks.

Grand Challenge: Engineer the tools of scientific discovery.
