We are looking for a creative, energetic, and self‑motivated Experimental Physicist to join our Processor Development (PD) team. In this challenging and exciting role, you will contribute to the development of superconducting gate‑model quantum processors, with a focus on long‑term scalability. You will leverage your expertise in gate‑model quantum computation as well as D‑Wave’s extensive experience in developing large‑scale superconducting integrated circuit control, and you will work collaboratively with a multidisciplinary team including superconducting circuit designers, fabrication engineers, software developers, physicists, and engineers to push the boundaries of quantum computing.

• Contribute to the conceptualization and design of scalable multi‑qubit superconducting quantum processors.
• Develop and run experiments, analysis routines, and quantitative models to characterize parameters and performance of as‑fabricated superconducting quantum processors.
• Perform coherence measurements (T1, T2, Ramsey, echo, noise spectroscopy) to identify decoherence mechanisms and use those data to guide improvements in device design, control, fabrication, and cryogenic infrastructure.
• Develop, calibrate, and validate high‑fidelity single qubit and two qubit gates, plus reset and readout, using standard benchmarking protocols.
• Diagnose scaling limitations in control, calibration, readout, and noise and develop methods to improve or circumvent these limitations.
• Collaborate with designers on device parameter studies and simulations and help define measurement primitives and requirements for improved processor performance.
• Share your results and ideas with the broader PD team through regular and clear documentation.
• Create and contribute to our software infrastructure for modeling, calibrating and operating qubits and processors.

• Ph.D. or M.Sc. in quantum computing or a related experimental field, or equivalent academic or industrial research experience.
• Experience with measurement and control of qubits using microwave techniques or other closely related quantum control topics and methods.
• Strong critical thinking and technical problem‑solving skills.
• Skill in independent research and evidence of deep understanding in your area of expertise.
• Ability to learn new technical topics quickly and effectively.
• Strong software development experience for experimental automation, data acquisition, and data analysis, with willingness to learn new languages and tools as needed.
• A collaborative mindset, a demonstrated ability to work effectively on an interdisciplinary team, and a strong commitment to the company’s success.
• Excellent communication skills and experience with summarizing technical information for a broad audience.
• Ability and willingness to adapt to shifting priorities in a time‑sensitive environment.

• A solid background in one or more of the following: quantum control of superconducting devices, superconducting device fabrication, RF or microwave engineering, and low‑noise electronics.
• Experience calibrating and characterizing superconducting qubits.
• Familiarity with methods to…
