Quantum computing has the potential to unlock new computational capabilities by enabling fault-tolerant systems. However, building a scalable, error-corrected quantum computer is not just a “quantum” problem—it presents significant systems and architectural challenges. Addressing these challenges early and from a broad perspective is essential for progress. In this talk, I will focus on two critical issues that shape the path toward fault-tolerant quantum computing. First, role system architecture in improving the fidelity of logical qubits. Second, there is a need for specialized compilation frameworks to support the constraints and requirements of early fault-tolerant quantum systems. By tackling these challenges, we can move closer to realizing scalable quantum computing.

Swamit Tannu is an Assistant Professor in the Computer Sciences department at the University of Wisconsin-Madison, where he leads the QUEST Research Group. His research focuses on developing architectural and systems abstractions for quantum computers to enable scientific discovery at scale. Swamit’s work has been recognized with the NSF CAREER Award, the Stamatis Vassiliadis Best Paper Award at Computing Frontiers, and also been inducted into the MICRO Hall of Fame.  Swamit earned his Ph.D. from Georgia Tech in 2020 before joining the University of Wisconsin-Madison.
