Summary
🤩
Rockstar🎓
Top SchoolJulian Kelly is a senior hardware leader and experimental quantum physicist with 15 years of experience driving Google's quantum processor roadmap from lab prototypes to milestone demonstrations. He led design of the 72-qubit Bristlecone processor and developed Optimus, an automated calibration framework that became the operational backbone for Google’s quantum processors. His PhD work at UCSB on Xmon transmons delivered record fidelities and helped enable early demonstrations of quantum error correction, contributions that fed directly into Google's 2019 quantum supremacy and 2022 error-correction milestones. Based in Santa Barbara, he blends hands-on device design, control-software engineering, and team leadership while steering efforts toward a long-lived, error-corrected logical qubit. An uncommon strength is his ability to translate delicate experimental advances into scalable systems and operational tooling used across large quantum teams.
