Lead Quantum Engineer, Readout

Job Description

Job Title: Lead Quantum Engineer, Readout. Location: Berkeley, CA

Responsibilities:

• Lead Rigetti’s experimental programs to characterize and improve the full readout stack for superconducting qubits.
• Develop theoretical models for readout performance and design readout circuits optimized for fast, high-fidelity operation.
• Identify and implement novel measurement techniques and pulse optimizations to enhance readout performance using Rigetti's Python-based calibration software.
• Collaborate with hardware and device design teams to design shortloops and test chips aimed at isolating aspects of the full readout stack to accelerate R&D.
• Develop fast qubit reset protocols to enhance circuit execution and enable error-correcting codes;
• Optimize readout for quantum error correction, ensuring high fidelity, rapid mid-circuit measurement, and ancilla readout;
• Work closely with diverse teams of engineers and scientists in device theory, algorithms, software, control hardware, chip design, and gate operation.

Qualifications:

• Ph.D. in Physics, Applied Physics, Electrical Engineering, or a related field, with at least 2 years of industry or postdoctoral experience.
• Expertise in circuit quantum electrodynamics and dispersive readout.
• Strong ability to perform measurements on quantum systems and explain results through theory and/or simulation.
• Exposure to superconducting qubits in academic or industrial settings;
• Experience in software development, particularly with Python, C, C++, or Rust;
• Experience with low-level pulse optimization of quantum gates or readout;
• Excellent communication skills and the ability to work in a collaborative team environment.

Benefits /Instructions:

• Base salary: $190,000 - $230,000 per year, with final compensation determined by experience, skills, and location.
• Comprehensive benefits including equity, medical, dental, and vision coverage, a 401(k) plan, paid parental leave, rejuvenation days, and vacation days aligned with local regulations and industry standards;
• Rigetti is committed to fostering a diverse and inclusive culture, encouraging applications from women, minorities, and underrepresented groups.
