Quantum Computing Technology and Roadmap
Abstract
The progress of Quantum Computing has significantly accelerated in recent years due to increased resources for research and development across the world. The focus has changed from just building quantum devices to establishing a quantum computing system including software and applications. An overview of the recent advancements of superconducting quantum computing systems is provided including the achievements made to scale processors to 127-qubit and scale up to 4000 qubits in 2025. Three key metrics are defined, scale, quality, and speed to holistically measure performance. The computational capabilities of today's quantum chips can be extended by adding classical resources using circuit knitting techniques to reach quantum advantage.
