What quantum software technology, s.l. (qst) does
Quantum Software Technology, S.L. (QST) is a Madrid-based private company founded in October 2017 that develops and commercializes QuantumPath® (QPath®), a device-agnostic Business Stack platform for professional quantum software development and execution. The platform provides an integrated quantum IDE (qIDE) that manages the full quantum software lifecycle — from algorithm creation through development, testing, implementation, deployment, and reuse — and is built from modular components including Q Assets Compositor® (visual algorithm design), qSOA® (quantum/classical IT integration), Q Agnostic QAOA® (cross-provider optimization), Q Risk Management® (technology risk mitigation), and Q PrivateHub®, Q|MGMT®, and Q|GovCenter (enterprise governance). QuantumPath® operates as a Quantum Software-as-a-Service (QSaaS) runtime that executes the same algorithms on hardware from Amazon Braket, D-Wave, Fujitsu, IBM, IonQ, OQC, and Rigetti and on QuTec simulators without vendor reprogramming.
The company monetizes through four subscription tiers (Free Developer, Developer, Business, Enterprise), professional services for organizations implementing hybrid quantum/classical systems, and a QuantumPath® Marketplace that enables third-party creators of quantum solutions and algorithms to commercialize their work. Go-to-market combines a product-led growth motion centered on the free experimentation tier with an enterprise field-sales motion for the governance and professional-services stack. Marketing is anchored on the Talavera Manifesto for Quantum Software Engineering (172+ endorsers), the QANSWER International Workshop held in Talavera de la Reina in February 2020, and a bilingual English/Spanish web presence.
QST holds European patent EP4231204 and Spanish patent ES3061321 T3 covering the QuantumPath® system, together with a portfolio of registered trademarks, and operates as the exclusive distributor of the platform. The company is privately held; publicly disclosed information is limited to its Madrid registered office at C/Viriato 9, active recruitment of physicists, mathematicians, chemists, and software engineers, and the global reach implied by its hardware-provider integrations.

quantum software technology, s.l. (qst) competitors and assessment
Company assessmentDirect peers
- Classiq Technologies: Classiq provides a quantum software development platform with a high-level modeling environment and automated synthesis to multiple hardware providers — a direct competitor to QuantumPath®'s qIDE and Q Assets Compositor® in the vendor-agnostic quantum software tooling category.
- Zapata AI: Zapata AI (now Zapata Computing) offers the Orquestra platform for building and deploying quantum and quantum-inspired workflows across multiple providers, competing head-on with QPath® as an enterprise-grade orchestration and lifecycle management platform.
- Strangeworks: Strangeworks provides a quantum computing platform that aggregates access to multiple hardware providers and offers subscription-based developer and enterprise tiers, very similar to QuantumPath®'s multi-provider QSaaS positioning.
- QC Ware: QC Ware develops quantum software (Promenade, Forge) and enterprise services for hybrid quantum-classical algorithms, comparable to QST's combination of a quantum software platform plus professional services for large organizations.
- 1QBit: 1QBit builds quantum and quantum-inspired software platforms for enterprise customers in finance, materials, and optimization, overlapping with QuantumPath®'s hybrid quantum/classical software development and industry-application focus.
Broad incumbents
- IBM Quantum: IBM Quantum offers the Qiskit SDK plus IBM Cloud access to IBM hardware, and represents a broad incumbent with the resources to integrate vendor-agnostic features natively — the dominant competitive threat to QPath®'s agnostic positioning.
- Amazon Braket: Amazon Braket is AWS's managed quantum computing service providing multi-provider access (IonQ, Rigetti, OQC, D-Wave, etc.) — both a QPath®-supported backend and a potential competitor that could bundle orchestration tooling into AWS itself.
- Microsoft Azure Quantum: Azure Quantum offers cloud access to multiple quantum hardware providers plus the Q# / QDK ecosystem, representing the broad hyperscaler incumbent that could absorb QPath®'s agnostic orchestration functionality.
- Xanadu: Xanadu builds photonic quantum hardware and the PennyLane software framework for hybrid quantum-classical machine learning — overlapping with QST on the software/developer-tooling side while also being a hardware provider QPath® could integrate.
- Quantinuum: Quantinuum (Honeywell/Cambridge Quantum merger) offers trapped-ion quantum hardware plus the TKET quantum software stack — a vertically integrated quantum hardware-and-software incumbent that competes for the same enterprise quantum software budget as QST.
