Unlocking Fault-Tolerant Quantum Computing: The Critical Role of Systems and Architecture

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.
