Dr. Tanay Roy is an Associate Scientist at the Superconducting Materials and Systems (SQMS) Center at Fermilab and serves as Deputy Head of the Architectures & Use Cases Thrust. His research focuses on developing next-generation quantum computing and sensing architectures based on three-dimensional superconducting radio-frequency (SRF) cavities, with the aim of building prototype quantum processors and sensors that achieve dramatically improved coherence times, enhanced controllability, and increased sensitivity. Dr. Roy’s work centers on high-dimensional bosonic quantum systems (qudits), which offer promising advantages over conventional qubit-based approaches for scalable quantum information processing. His broader research interests include quantum algorithms, quantum error correction, and identifying near-term quantum utility for real-world–inspired applications.
Prior to joining Fermilab, Dr. Roy was a postdoctoral researcher at the University of Chicago, where he worked on autonomous quantum error correction and quantum search algorithms and demonstrated a qutrit-based quantum processor. He received his Ph.D. from the Tata Institute of Fundamental Research (India), where he co-developed broadband superconducting parametric amplifiers and contributed to the development of India’s first three-qubit superconducting processor.
