Tokyo, Japan and Broomfield, Colorado, January 29th, 2025 — SoftBank Corp. ("SoftBank") and Quantinuum ("Quantinuum") announced they agreed to a wide-ranging partnership in quantum computing.
By combining their respective strengths, both companies will unlock innovative quantum computing solutions that will overcome the limitations of classical artificial intelligence (AI) and realize next-generation technologies.
This unique initiative coincides with the International Year of Quantum Science and Technology (IYQ) in 2025, and it is expected to ignite new business opportunities through the dynamic fusion of AI and quantum computing.
The Necessity of Quantum Computing Beyond the Limits of AI
In this modern era, AI is delivering impressive results across various domains. However, it is widely recognized that there are still significant challenges that AI alone is struggling to overcome. Complex optimization problems, deciphering causal relationship analysis, and conducting high-precision simulations based on fundamental equations remain formidable obstacles for current AI technologies.
Moreover, the hybrid approach that combines Central Processing Units (CPUs), Graphics Processing Units (GPUs), and Quantum Processing Units (QPUs) holds the potential to further extend the capabilities of AI. By leveraging the unique strengths of each type of processing unit, hybrid systems can execute more advanced and diverse computations, providing innovative solutions that surpass traditional limitations.
SoftBank and Quantinuum believe in the power of quantum computing and are committed to exploring its transformative potential.
Current State and Challenges of Quantum Computing
Despite impressive growth in the quantum computing sector, several technical and business challenges need to be addressed to advance the state-of-the-art so that quantum computers are used to solve practical problems.
(1) Building a Business Model
- Initial Investment and Operational Costs: The substantial initial investment and operational costs required for the development and deployment of quantum computers lack concrete cost recovery strategies, which in turn suppresses the drive for companies to develop and adopt the technology.
- Clarification of Revenue Models: The business models for generating revenue, including the methods of offering quantum computers and setting usage fees, have not yet been fully realized.
(2) Establishing Specific Use Cases
- Discovering Use Cases: There is a shortage of use cases that clearly demonstrate which fields quantum computers will be useful in. Understanding the market size and revenue models through clear examples, especially in areas such as quantum chemical calculations and machine learning, is necessary.
- Understanding the Market and Revenue Predictions: It is crucial to specifically identify the areas where computations can only be performed by quantum computers and are commercially viable, as well as to predict the timing and scale of these applications.
(3) Advancing Hardware and Software Technologies
- Limitations and Challenges of Hardware: The current hardware performance (number of qubits and operation precision) of quantum computers is inadequate for handling practical problems, and significant enhancements in performance are needed for practical use.
- Software Development and Error Mitigation: The development of hybrid algorithms that combine traditional methods, as well as advancements in error suppression, mitigation, and correction technologies, are essential to enable practical computations. Furthermore, developing technologies that mutually complement hardware and software are also indispensable.
- Timing for Service Provision: Making decisions based on a deep understanding of technology to provide services at the optimal timing requires assessing the speed of technological advancements and market needs.
Key Activities
SoftBank and Quantinuum are committed to addressing these challenges together to advance the practical application of quantum computers.
(1) Joint Market Research & Business Model Development for Quantum Data Center
- With a view toward the realization of a "quantum data center" capable of performing advanced calculation processing by combining CPUs, GPUs and quantum computers (QPUs), both companies will use the Japanese market as a foothold to conduct global market research in the Asia-Pacific region and other regions, and explore specific business models based on that research.
- Both companies will jointly consider methods to reduce investment risks, such as revenue sharing and cost sharing.
(2) Construction of Quantum Use-Case Timelines and Validation
- SoftBank will provide its own business challenges as use cases.
- Both companies will clarify use cases in quantum chemistry and network analysis, and construct a timeline showing when these use cases will be realized. In quantum chemistry, the search for new optical switch materials for All Optical Networks is anticipated, while in network analysis, the application to anomaly detection and fraud detection in SoftBank's communication network is envisioned.
- Both companies will develop software technology that makes effective use of limited hardware resources, and explore methods for linking CPUs, GPUs, and QPUs.
