Fixstars Amplify Expands Quantum Computer Providers and Algorithms

IRVINE, California – May 22, 2026 – Fixstars Corporation (TSE Prime: 3687; President and CEO: Satoshi Miki), a leading company in performance engineering, today announced that its group company Fixstars Amplify Corporation (President and CEO: Yoshiki Matsuda) has launched Amplify Quantum, a new extension to the Fixstars Amplify SDK—a software development environment for quantum computing—that significantly enhances support for optimization on quantum computers.

The Fixstars Amplify SDK has long provided a unified development environment for solving combinatorial optimization problems across a wide range of quantum annealers and Ising machines. With Amplify Quantum, users can now connect more easily to IBM Quantum^[1], Qulacs^[2], and Amazon Braket^[3]*, further strengthening support for quantum computers. The newly added Amazon Braket integration, in particular, significantly expands the range of available solvers.

* Users are responsible for obtaining the relevant licenses.

Accelerating R&D on Quantum Optimization

Quantum computers vary widely in qubit count, error rates, and other characteristics depending on the provider and device. Unlocking their full potential therefore requires identifying the optimal device-algorithm pairing from a broad set of options.

Amplify Quantum is designed to meet these advanced R&D needs and provides a platform to support the future development of quantum computing through the following features.

Key Features of Amplify Quantum

Seamless access to diverse computing resources: Amazon Braket provides access to quantum computers from multiple vendors, substantially expanding the choice of available quantum hardware and simulators. By simply swapping the SDK's client class, users can run optimizations and benchmark performance across different quantum devices using a single, unified codebase, eliminating the need for device-specific programming.

Expanded support for algorithms: In addition to the previously supported Quantum Approximate Optimization Algorithm (QAOA) ^[4], Amplify Quantum now supports several other leading quantum optimization algorithms, allowing users to select and execute the best-suited algorithm for each device's characteristics.

Support for additional quantum computers and algorithms will continue to expand over time.
