What Fixstars Amplify does
Fixstars Amplify Corporation, a wholly owned subsidiary of Fixstars Corporation established on October 1, 2021 and headquartered in Minato-ku, Tokyo, operates a cloud-based platform for combinatorial optimization that combines a Python SDK (Amplify SDK) with a proprietary GPU-based annealing engine (Fixstars Amplify AE) and unified access to third-party quantum and Ising solvers including D-Wave, Fujitsu Digital Annealer, Toshiba SQBM+, IonQ, IBM Quantum, Hitachi CMOS Annealing, Amazon Braket, QUDORA, Qulacs, Rigetti, AQT, IQM, NEC, and Gurobi. The platform abstracts hardware-specific complexity behind a single Python API so customers can formulate QUBO/Ising problems once and dispatch them to any supported solver, with add-on modules (Amplify Quantum for gate-based QC and QAOA variants, Amplify-BBOpt for black-box / FMQA-style optimization, and Amplify Scheduling Engine for scheduling workloads) extending coverage beyond pure annealing.
The product is sold via a self-serve freemium funnel — free individual tier plus Individual paid plans at $1,000–$3,000/user/month and Business plans at $2,000–$6,000/app/month — augmented by quote-based enterprise contracts, optional solver add-ons (e.g., Toshiba SQBM+ at $3,000/user/month), and consulting / development services. Customers include Japanese industrial enterprises (Mazda, Sumitomo Corporation, Toyota via a Sumitomo joint solution, Nippon Television Network, Nomura Research Institute) and academic institutions (University of Tokyo, Waseda, Keio), with the company reporting 1,200+ organizations using the platform and pursuing flagship research collaborations with NTT, RIKEN, the University of Tokyo, NICT, and OptQC on a five-year quantum roadmap targeting 10,000 qubits by 2027 and 1,000,000 qubits by 2030.
Fixstars Amplify holds ISO/IEC 27001:2022 / Amd 1:2024 (JIS Q 27001:2025) ISMS certification (Registration No. ICMS-SR0754, dated May 26, 2026) and is wholly capitalized at ¥50M by parent Fixstars Corporation, with no external funding rounds, public revenue disclosure, or M&A activity reported.

Fixstars Amplify product offering
Product offeringCore offering
Fixstars Amplify is a cloud-based quantum computing platform that provides a Python SDK and execution environment for solving combinatorial optimization problems via Ising machines, quantum annealers, and gate-based quantum computers. The platform includes the proprietary Fixstars Amplify AE (GPU-based Annealing Engine) and offers vendor-neutral access to third-party solvers from D-Wave, Fujitsu, Toshiba, IBM, IonQ, Hitachi, and others. Customers formulate problems in Python and execute them on any supported solver through a unified API, supporting both individual developers and enterprise R&D teams.
Product overview
Fixstars Amplify is a single, integrated cloud platform rather than a loosely bundled suite. The architecture is platform-plus-modules: the Fixstars Amplify Cloud serves as the execution backbone (containing the Fixstars Amplify API, the proprietary Fixstars Amplify AE annealing engine, and the Fixstars Amplify Scheduling Engine), the Amplify SDK is the Python library used to formulate combinatorial-optimization problems and dispatch them to any supported solver, and add-on modules — Amplify Quantum (gate-based quantum computing and QAOA/RQAOA), Amplify-BBOpt (black-box optimization), Amplify AE Enterprise, manufacturing-specific solutions, and development services — extend the platform to specific workloads. The platform is compatible with third-party Ising/quantum annealing machines (Fujitsu Digital Annealer, Toshiba SQBM+, D-Wave 2000Q/Advantage, Hitachi CMOS), gate-based quantum computers (IBM Quantum, IonQ, Rigetti, IQM, AQT, QUDORA), simulators (Qulacs, Qiskit Aer, Amazon Braket), and MIP solvers (Gurobi, NEC), all accessed through the same SDK.

- Fujitsu (Digital Annealer): Fujitsu's Digital Annealer is a quantum-inspired Ising solver delivered as a cloud service and is both an integrated partner solver on Fixstars Amplify and a competing standalone offering for enterprise combinatorial optimization, making it a direct peer and channel partner simultaneously.
- Toshiba Digital Solutions (SQBM+): Toshiba's Simulated Bifurcation Machine (SQBM+) is a quantum-inspired Ising solver sold as a standalone cloud product and as an add-on option through Fixstars Amplify, directly competing for enterprise optimization customers in the same buyer segment.
- Hitachi (CMOS Annealing Machine): Hitachi operates a CMOS Annealing Machine cloud service targeting the same enterprise combinatorial optimization workloads as Fixstars Amplify, and is both an integrated solver partner on the Fixstars platform and a direct standalone competitor.
Emerging players
- Multiverse Computing: Multiverse Computing is a quantum-inspired software company focused on combinatorial optimization and finance/manufacturing use cases, competing for the same enterprise optimization workloads that Fixstars Amplify targets via its GPU annealing engine and QUBO formulations.
Broad incumbents
- IBM Quantum: IBM Quantum is the broad incumbent in gate-based quantum computing with Qiskit and IBM Cloud, offering a competing developer platform and SDK that targets the same enterprise R&D audience and that Fixstars Amplify integrates with as a partner.
- Amazon Braket: Amazon Braket is AWS's multi-vendor quantum cloud service, aggregating access to D-Wave, IonQ, Rigetti, IQM, and others; it competes with Fixstars Amplify as a multi-solver abstraction layer for cloud customers while also being one of its integrated solver partners.
