Toshiba Brings SQBM+™, its Quantum-Inspired Optimization Solution,
to Microsoft Azure Marketplace

February 6, 2024
Toshiba Digital Solutions Corporation

Toshiba Digital Solutions Corporation (Toshiba Digital Solutions), an industry leader in applying quantum-inspired solutions to complex real-world problems, today launched SQBM+ for Azure, a version of its SQBM+ software customized for the Azure Marketplace operated by Microsoft Corporation.

SQBM+ for Azure joins the version already available on Amazon Web Services, and underlines Toshiba Digital Solutions’ determination to make SQBM+ available to customers working in different IT environments.

Optimization software quickly finds optimal solutions among an immense number of options. SQBM+ is derived from the Simulated Bifurcation Machine, a combinatorial optimization solver built on the quantum-inspired Simulated Bifurcation Algorithm developed by Toshiba Corporation. It runs on standard computers and finds high-precision, approximate solutions (high-quality solutions) to complex, large-scale problems in a short time. 

The commercial launch of SQBM+ allowed Toshiba Group and its partners to verify the practicality of SQBM+ and the effectiveness of applying quasi-quantum computing to high-speed, high-frequency stock trading1, computational drug discovery2, energy management, and materials development. Toshiba Digital Solutions aims to leverage SQBM+ across numerous fields, and to contribute to the resolution of complicated problems.

Key Features of SQBM+ for Azure
1.Provided as an Azure Virtual Machine

  • Starting to use SQBM+ is quick and easy, as the preconfigured Azure virtual machine launches an instance of the software. There is no need to install SQBM+.
  • The SQBM+ instance is exclusive to the user and quickly processes all requests. As it is an exclusive copy, users have full control of the resource and its capabilities, including auto-scale, redundancy, and start/stop.
  • Can be embedded in the customer’s system to reduce network overhead.

2.SQBM+ Version 23 supports 10 million variables and improves scale, speed, and accuracy

  • SQBM+ Version 2 supports a quadratic unconstrained binary optimization (QUBO) solver capable of handling QUBO problems with up to 10 million variables.
  • An improved algorithm speeds up the search for an approximate solution and improves accuracy.
  • Toshiba Digital Solutions has enhanced SQBM+’s capabilities by offering extended functions and solvers to improve usability and overall performance.
    -       PUBO4 solver: A solver that supports cubic and quartic problems.
    -       QPLIB5 solver: For linearly constrained quadratic binary programming problems. 

3.Availability on Azure Marketplace
Azure Marketplace is an online store for certified, optimized solutions built on or for Azure, and is intended for IT professionals and developers. Azure Marketplace is the premier destination for your software needs - certified and optimized to run on Azure.

Pricing of SQBM+ for Azure
Two plans are available for SQBM+ for Azure: Learn & Development is designed for learning, evaluation, and development purposes; Business Standard is tailored for business operations.
