The Superconducting Quantum Materials and Systems Center (SQMS) at Fermilab seeks a Quantum Postdoctoral Research Associate – 3D Cavity Quantum Hardware to support critical research within the center. The role focuses on advanced superconducting quantum hardware, especially 3D cavity‑based quantum processing units and ultra‑coherent superconducting cavity platforms for quantum information processing. The successful candidate will conduct independent research under guidance from senior scientists, contributing to the development, measurement, control, and integration of next‑generation quantum systems, and help maintain technical continuity for key SQMS deliverables.

• Conduct research in superconducting quantum hardware, with emphasis on 3D cavity‑based quantum processing units, bosonic modes, qudits, and circuit QED systems.
• Design, simulate, build, install, commission, and characterize new or upgraded elements of superconducting quantum experiments, including ultra‑coherent 3D cavities, ancilla qubits, tunable couplers, microwave control and readout hardware, filters, interconnects, and cryogenic measurement systems.
• Develop and implement experimental techniques for quantum control, readout, calibration, and characterization of multimode superconducting quantum systems.
• Contribute to the development of large‑dimensional bosonic qudits and multimode quantum processors for quantum computing, HEP‑relevant quantum simulation, and hardware‑efficient quantum information processing.
• Participate in data acquisition, conduct analysis, develop models and simulations, and present or publish outcomes at conferences and or in refereed journals.
• Contribute to research directions relevant to bosonic quantum information processing, modular superconducting quantum architectures, error‑detected or error‑corrected operations, quantum interconnects, and related quantum sensing applications.
• Work collaboratively with Fermilab scientists, engineers, technicians, students, postdocs, and external collaborators across the SQMS Center.
• Perform other duties as assigned by the supervisor.
• Abide by all environmental, health and safety regulations and practices pertinent to this position.

• Appointees usually have recently completed their PhD (often within the last two years) or are expected to complete it within the current calendar year.

• Demonstrated potential to make contributions that qualify for appointment as an Associate Scientist.
• Strong background in quantum mechanics and experimental physics, applied physics, electrical engineering, or related fields.
• Knowledge of superconducting quantum circuits, microwave resonators, circuit QED, quantum measurement, or related quantum hardware platforms.
• Ability to work independently while contributing effectively to a highly collaborative research environment.
• Ability to communicate effectively through written reports, presentations, publications, and technical discussions.
• Self‑motivation, scientific curiosity, and interest in developing next‑generation superconducting quantum hardware platforms.

• Experience with superconducting qubits, 3D cavities, microwave resonators, bosonic modes, qudits, tunable couplers, or related superconducting quantum systems.
• Experience with cryogenic microwave measurements, quantum control, microwave electronics, RF engineering, or low‑temperature experimental techniques.
• Experience with multimode quantum control, bosonic encoding, qudit operations, error‑detected operations, or quantum processor calibration.
• Experience with device modeling, electromagnetic simulation, circuit simulation, Hamiltonian modeling, or numerical analysis of quantum systems.
• Experience with experimental automation, calibration, data acquisition, and data analysis.
• Interest in the intersection of superconducting quantum computing, bosonic quantum information, modular quantum architectures, and HEP‑relevant quantum applications.

• Onsite:
  This is an onsite role, and the candidate must be able to work from the Batavia office.

• Medical, Dental, Vision and Flexible Spending Account.
• Paid time‑off.
• Life insurance.
• Short and Long‑term disability insurance.
• Retirement benefits.
• Onsite day care.
