Drawing from your expertise in circuit Quantum Electrodynamics and full-wave radio-frequency engineering, from fundamental theory through practical application, you will identify and implement improvements to the integrated circuit layout to mitigate loss and crosstalk channels. You will lay out and design microwave multi-qubit circuits for fabrication and develop next-generation quantum processors.

Key responsibilities include designing, laying out, and simulating superconducting microwave integrated circuits for quantum processors, with a focus on optimal on-chip signal delivery (routing, filtering, multiplexing, etc…). You will also simulate the full-wave electromagnetic performance of quantum processors (eigenmode & driven analyses) using commercial finite element software, engineering the mode profile of resonant structures and the coupling between these resonant structures and on-chip feedlines to optimize device performance.

Engagement with quantum engineers to identify and optimize Hamiltonian parameters for our R&D test devices and deployed quantum processors is also required. Additionally, you will map between target quantum Hamiltonians and integrated circuit layouts using internal python software libraries to construct and diagonalize the quantum Hamiltonian.

Interpretation of simulation and experimental results to identify and mitigate loss and crosstalk channels, or other undesirable microwave properties of the circuit, is essential. Collaboration with fabrication and experimental teams to develop novel processor architectures is also expected.

A PhD in Physics, Applied Physics, Electrical Engineering, or a related field, or the equivalent experience in industry and 3+ years of industry experience is preferred. Strong background in the theory and application of circuit Quantum Electrodynamics to the design of superconducting qubit based quantum processors is also required.
