SQBM+ is a quantum-inspired optimization solution based on the Simulated Bifurcation Machine (SBM) that is a combinatorial optimization solver utilizing the Simulated Bifurcation Algorithm (SB Algorithm) developed by Toshiba Corporation. We offer a lineup of optimization solvers according to the intended application, and have adopted a new SB Algorithm that greatly improves speed, accuracy, and scale.
For many social and industrial challenges, combinatorial optimization is essential for selecting the optimal items from an enormous range of choices; for example, optimizing financial transactions, the movement of industrial robots, travel and transmission routes, and molecular design for drug discovery. When using existing computers, combinatorial optimization is difficult to solve at high speeds because the number of combination patterns increases exponentially as the scale of the problem grows. For this reason, specialized combinatorial optimization computers are being actively developed in Japan and overseas.
Toshiba Group is verifying the effectiveness of SBM. For example, we are starting joint verification for the effectiveness of applying pseudo-quantum computers to high-speed and high-frequency trading in the stock market. This solution uses existing computers and utilizes SBM, which enables high-precision approximate solutions (good solutions) for complex and large-scale problems to be obtained in a short time. Additionally, the PoC (Proof-of-Concept) version of SBM was released to the world on the AWS Marketplace operated by Amazon Web Services Inc. We have been searching for real problems in order to solve social issues in a variety of fields by cooperating with research institutions such as universities, as well as with corporations aiming to solve social issues as actual problems in combinatorial optimization . We provide systematized SQBM+ as a solution by utilizing the results of business co-creation efforts aimed at developing new markets and creating new solutions by using SBM technology, as well as the knowledge gained through various verification experiments in Japan and overseas. SQBM is an acronym for “Simulated Quantum-inspired Bifurcation Machine,” which means that it is derived from SBM that implement the SB Algorithm invented in the research process for quantum computers at Toshiba's R&D centers. The “+” indicates that this solution includes various services and indicates our intention to continuously strengthen the solution.
we provide cloud services for SQBM+ in Azure Quantum, which is a full-stack public cloud ecosystem for quantum solutions published by Microsoft Corporation, and execution modules on the current AWS Marketplace. We also plan to provide on-premise versions for highly-confidential applications not suitable for cloud environments and applications that require ultra-low latency, and to embed those versions in partner applications or provide them on an OEM basis. Furthermore, we will provide professional services such as education and support for formulation.
