What SaxonQ does
SaxonQ GmbH is a Leipzig-based deep-tech startup founded in 2021 by Prof. Dr. Marius Grundmann and Prof. Dr. Jan Meijer (both from Leipzig University) that develops and manufactures mobile quantum computers based on Nitrogen-Vacancy (NV) center technology in diamond chips. Unlike most quantum hardware competitors, SaxonQ's systems operate at room temperature from a standard wall outlet, requiring no cryogenic cooling, vacuum chambers or complex lab infrastructure. The current flagship is the third-generation QC2026 DUAL CORE, featuring two independently controllable quantum processor cores with five qubits each, designed to scale to multi-core architectures. Earlier generations include the 4-Qubit Demonstrator that became the first system to pass DLR's Quantum Computing Initiative acceptance tests.

SaxonQ partnerships and signals
Strategic signalPartnerships
Five partnerships are on record, tiered core and minor.
- DLR Quantencomputing-Initiative (QCI Connect)coreSaxonQ connected its mobile quantum computer to QCI Connect - the quantum computing platform of DLR Quantum Computing Initiative. This enables industrial partners, research institutions, and startups to access computing time on real qubits through API.
- Fraunhofer IWU (Fraunhofer Institute for Machine Tools and Forming Technology)coreFraunhofer IWU in Dresden operates Saxony's first mobile quantum computer (4 qubits) since June 2025. The system is used for Industry 4.0 solutions and cognitive production research. Fraunhofer IWU also uses SaxonQ's API for direct integration. Partner in SAX-QT research network.
- Quantum MachinescoreQuantum Machines provides advanced hybrid quantum-classical control solutions. Their OPX+ high-precision microwave electronics system enables precise and dynamic qubit control in complex real-world environments, making it a key enabler of SaxonQ's room-temperature quantum computer.
- Bechtle IT-Systemhaus BonncoreSales partnership effective April 1, 2025. Bechtle adds SaxonQ's quantum computers to its product portfolio and enables companies early access to this technology. In 2026, Bechtle completed certification for sales, integration and operation, becoming SaxonQ's first certified partner.
- Quantum Business Network (QBN)minorSaxonQ joined the Quantum Business Network - the world's leading network for business development and innovation in quantum technologies and their value chains. The network promotes growth acceleration, collaboration, and dialogue between industry, science, and politics in Europe and Germany.

SaxonQ competitors and assessment
Company assessmentPeers
Broad incumbents
- Pasqal: French neutral-atom quantum computing company building both on-premises systems and cloud access. Comparable in being a European deep-tech quantum hardware startup that has scaled beyond research demonstrators and pursues industrial customers—though its modality (neutral atoms) differs from SaxonQ's NV diamonds.
- IonQ: NYSE-listed trapped-ion quantum computing company offering cloud-accessible systems via AWS, Azure, and Google Cloud. Direct competitor in the "industrial quantum" narrative and enterprise cloud-API GTM motion that SaxonQ pursues via QCI Connect, but using a different (trapped-ion) physical substrate.
- Rigetti Computing: Nasdaq-listed superconducting quantum computing company offering hardware systems and a cloud platform (QCS). Competes with SaxonQ on multi-qubit gate-fidelity engineering and on cloud API business models, but uses a different physical approach (superconducting transmon qubits).
- Google Quantum AI: Google's quantum computing division, known for Sycamore and Willow superconducting processors and demonstrated below-threshold error correction. A broad quantum hardware incumbent and platform competitor whose roadmap pressures SaxonQ's qubit-count credibility, though operating in a different (superconducting) physical modality.
- IBM Quantum: Division of IBM operating the largest superconducting quantum systems in market (1,121+ qubit Condor) and a public cloud platform (IBM Quantum Platform). Overlaps with SaxonQ on quantum hardware manufacturing and cloud API access, but uses a fundamentally different physical approach (superconducting transmon, requiring dilution refrigerators).
Direct peers
- Quantum Brilliance: Australia/Germany-based quantum computing company also using NV-center diamond technology for room-temperature quantum computers. Closest direct competitor: identical physical substrate (diamond NV centers), same go-to-market focus on edge/room-temperature deployment, and same target verticals (research, defense, industry). Both companies are racing to miniaturize to chip scale.

Does SaxonQ have an API?
Yes. SaxonQ's mobile quantum computer is network-capable via API. The company developed a proprietary framework for QCI Connect that accepts cloud jobs, validates them, forwards them to the quantum processor, and returns structured results. A digital twin of the quantum computer with simulated qubits enabled complete software development and testing before physical deployment. Additionally, SaxonQ integrated an API into their Gemstone software, enabling developers to embed the SaxonQ quantum computer directly into their own programs, query device and job status, and automatically retrieve results. Developer documentation is at www.saxonq.com/medien/whitepaper.
