The quantum research group in Fujitsu Research of America (FRA) is seeking an exceptional researcher to develop technologies that will be incorporated into Fujitsu's future quantum computer hardware. These technologies will be used to strengthen Fujitsu's quantum computing offerings in various fields such as healthcare, material science, and finance. The successful candidate will be based out of our Santa Clara office located in the San Francisco Bar Area in California and will require international travel on an ad-hoc basis.

Your role will involve theoretical and/or experimental research on development and improvement of superconducting quantum computers, aiming for fault-tolerant quantum computing. The research area is broad and there are several possible roles, so the roles will be discussed during job interviews.

Required Qualifications

• Ph.D. in Quantum Information Science, Quantum Physics, Solid-State Physics, Applied Physics, Electrical Engineering, or a closely related field
• Minimum of 3 years of academic or industry experience (after obtaining Ph.D) in the theoretical or experimental research of superconducting circuits, mesoscopic physics, and/or circuit Quantum Electrodynamics (cQED) with an excellent publication record.

Candidates are expected to possess deep expertise in at least one of the following areas, complemented by a strong foundational understanding of the others:

Theory & Modeling for Superconducting Quantum computer

• Demonstrated expertise in quantum mechanics, statistical physics, and electromagnetism, with the ability to apply these principles to quantumcomputers.
• Exceptional proficiency in numerical computation and advanced programming skills (e.g., Python, Julia, C++); extensive experience with specialized simulation tools such as COMSOL, Ansys HFSS, or custom-developed quantum simulation software is essential
• A deep and sophisticated understanding of hardware experiments, enabling insightful interpretation of experimental results, proactive identification of fundamental device challenges, and the ability to lead constructive, high-level technical discussions with experimental and engineering team.

Experimental Quantum computer

• Proven expertise in the design, modeling, measurement and optimization of superconducting quantum bits (e.g., transmons), including coherence engineering, anharmonicity control, and qubit-qubit coupling.
• Strong experimental data analysis skills, including noise characterization, error analysis, and statistical validation of experimental results.
• Experience with cryogenic experimental setups (e.g., dilution refrigerators, cryostats) and microwave measurement techniques (e.g., network analyzers, spectrum analyzers, arbitrary waveform generators) for quantum device characterization and control.
• Conduct those experiments at our facilities in Japan.

Fujitsu aligns salaries to the specific geographic location in which the work is primarily performed. It is not typical for an individual to be hired at or near the top of the range for their role and compensation decisions are dependent on the circumstances of each situation. The pay range for this role takes into account the wide range of factors that are considered in making compensation decisions including but not limited to: specific skills, qualifications, experience, and comparison to other employees already in this role. The pay range for this position is estimated at $187,500 to $210,000 USD. Additionally, this role may be eligible for a short-term incentive based on company results and individual performance. As a technology company, Fujitsu recognizes that human resources are its most important capital. To create an environment where all employees can work positively and healthily, both in mind and body, we offer a full range of health, 401K, and other benefits.

At Fujitsu, we are committed to creating a diverse and inclusive workplace where everyone feels valued and respected. We believe that diversity and inclusion are essential to our success, and we are committed to creating an environment where all employees can thrive.

We are an equal opportunity employer and qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, age, disability, marital status, sexual orientation, gender identity or expression, genetic information, veteran status, or any other characteristic protected by law.

We believe that everyone has something to contribute, and we are committed to creating a workplace where everyone can reach their full potential.
