• The companies have published a joint white paper mapping commercially relevant quantum computing use cases in quantum chemistry and graph analytics to Quantinuum’s hardware roadmap.
• The paper provides a framework for assessing how advances in quantum hardware and algorithms could affect when practical industrial applications become feasible.
• SoftBank Corp. and Quantinuum will use the roadmap to inform their exploration of future quantum AI data center services and related business models.

TOKYO and BROOMFIELD, Colo. – Quantinuum (NASDAQ: QNT) and SoftBank Corp. ("SoftBank") today announced the publication of “Quantum Computing Frontiers,” a joint white paper that maps two commercially-relevant quantum computing application areas against Quantinuum’s hardware roadmap. The analysis examines how advances in quantum hardware and algorithms could affect when these applications become practical for industrial use.

Building on this use-case roadmap, the paper also examines how quantum computing, AI, and high-performance computing could be integrated into future computing infrastructure. It considers how progress across successive hardware generations could inform future quantum AI data center services and related business models, a key focus of the Quantinuum and SoftBank partnership announced last year.

“The key takeaway of this study is that organizations do not need to wait for large-scale, fault-tolerant systems to explore where quantum computing can begin creating value,” said Duncan Jones, General Manager, Applications Group at Quantinuum. “By using today’s systems to develop, benchmark and refine applications in areas such as quantum chemistry and graph analytics, enterprises can build the technical and operational readiness needed for the next era of quantum-enabled computing.”

“The question is no longer whether quantum computing may deliver value, but rather which problem classes become executable at which stage of hardware maturity,” said Ryuji Wakikawa, Senior Vice President & CTO at SoftBank Corp. “However, we believe progress in hardware must be complemented by equally strong developments in quantum algorithms and the integration of quantum systems with AI and high-performance computing.”

The white paper discusses illustrative scenarios describing how representative applications, technology maturity, and potential market opportunities may evolve over time under stated assumptions. The analysis provided in the paper is intended to provide a conceptual framework for understanding potential market evolution and does not represent financial guidance or forecasts. These analyses are intended to support discussion of future technology development and should not be interpreted as commitments regarding commercialization, infrastructure investment, products, services, or financial performance.

The full white paper is available to download on the SoftBank and Quantinuum websites.
