Superlinear Computing · On-site at our Palo Alto HQ, with occasional travel to our Chicago Quantum Lab (Illinois Quantum and Microelectronics Park) · Full-time
About Superlinear Computing Superlinear Computing is a quantum hardware company headquartered in Palo Alto, with a lab at the Illinois Quantum and Microelectronics Park in Chicago. We design, deploy, and operate on-premises superconducting systems, apply machine learning to characterize quantum system behavior, and translate those findings into specialized hardware products.
The Role:
You will work with both quantum systems we operate: the superconducting hardware in our Chicago lab, run with full remote management, and the various entropy sources on the bench in our Palo Alto lab. You own calibration and characterization at the physics level, readout, error mechanisms, and the underlying noise
What You’ll Own Physics-level investigation of noise sources across the systems we operate, with statistical treatment rigorous enough to stand behind.
Characterization of the entropy sources we are developing.
Figures of merit for the ML-driven characterization pipelines our engineering team builds.
What We’re Looking For:
A Master’s degree (or an equivalent experimental record) in experimental physics, quantum optics, or precision measurement; PhD preferred.
A record of serious noise characterization: you have traced noise in a real measurement chain to its physical origins and defended the result statistically in quantum hardware, precision metrology, gravitational-wave detection, or optical systems.
Appetite for hard, patient, hands‑on work at a small company: you will sit with stubborn measurements until they are understood, not merely worked around.
Nice to Have:
Hands‑on superconducting qubit measurement: coherence measurements, dispersive readout, microwave control.
Grounding in the noise physics of lasers and optical detection: the fundamental, quantum-origin fluctuation processes and their technical counterparts, and how each is measured and told apart.
Dilution refrigerator experience at the operator level; microwave signal-chain fluency (IQ mixing, heterodyne readout, pulse shaping).
Familiarity with control stacks (Quantum Machines OPX, Qblox, QICK) and calibration frameworks.
Depth in TLS physics, flux noise, readout crosstalk, or amplifier-chain characterization.
Experience characterizing or validating entropy sources or randomness generation.
Statistics and ML on measurement streams.
Willingness to travel to the Chicago lab when the work calls for hands‑on time.
Compensation and Benefits: Base salary: $240,000 – $300,000, depending on experience. Equity in the company
Benefits:
Medical, dental, and 401(k).
Superlinear Computing is an equal opportunity employer.
