Why Error Awareness Matters: A Faster Path to Fault-Tolerant Quantum Computing Article Highlights In his latest post, Trevor takes a deeper look at D-Wave's gate-model roadmap, including our goal of reaching 100 logical qubits capable of more than one million error-corrected operations by 2032. He also explores the technologies underpinning that roadmap—from dual-rail qubits and on-chip cryogenic control to our forthcoming error-aware simulator—and why they matter for building practical, scalable gate-model quantum computers. For much of the quantum computing industry's history, progress has been measured by physical qubit count. But as the field matures, it is increasingly clear that qubit count alone will not determine who delivers commercially viable, fault tolerant gate-model quantum computers first. What really matters is a system's ability to execute operations reliably, efficiently, and at scale. That principle is at the heart of D-Wave's gate-model roadmap. D-Wave is pursuing a path to commercial fault-tolerant quantum computing with a goal of delivering 100 logical qubits capable of successfully performing more than one million operations by 2032. Our approach brings together several core capabilities: superconducting dual-rail qubits with built-in error detection, on-chip cryogenic control technology, deep expertise in scaling superconducting quantum systems, and an enterprise-grade quantum cloud infrastructure. Together, these technologies give D-Wave a differentiated path toward the performance, efficiency, and scalability required to make commercial gate-model quantum practical. To help developers start preparing for that future now, we recently announced our forthcoming gate-model quantum computing simulator. Expected to be the first-of-its-kind built for error-aware programming, the simulator is built around the dual-rail architecture that underpins our gate-model roadmap. It is intended to provide visibility into error-detection data so developers can prototype applications, develop error correction techniques, and build error-aware programming expertise they can carry forward as the roadmap advances. Once available through D-Wave's Leap™ cloud platform, the
