What JoS QUANTUM does
JoS QUANTUM GmbH is a Frankfurt am Main-based quantum technology company founded in 2018 that develops quantum algorithms for industrial use cases, primarily in financial services, security, and cryptography. The firm specializes in quantum amplitude estimation (QAE) for risk modeling and sensitivity analysis — including a stacked Grover-over-QAE construction delivering quartic speedup for identifying tail-risk drivers in the Deutsche Börse Group production risk model — and in Shor's algorithm resource estimation for cryptographic vulnerability assessment, plus ML-based security proofs for quantum key distribution. Its technical assets include three filed German patents (priority 2023-10-30) on ML-based QKD security proofs, peer-reviewed publications in Nature npj Quantum Information and other venues, and two self-serve browser demos (RISQ risk analytics and an RSA break estimator).
The business model is exclusively professional services and consulting, with no packaged software product. Revenue is generated through custom engagements ranging from 0.5–1 hour keynote presentations and 1–5 day training workshops to 3–24 month proofs of concept and ongoing strategy advisory for investors and corporate clients. Go-to-market combines direct enterprise sales (engagements initiated via [email protected]), research-led marketing through LinkedIn and academic publication, and product-led top-of-funnel via the interactive browser demos. Confirmed and partner counterparties include Deutsche Börse Group (production customer), Deutsche Bundesbank, DE-CIX, R+V Versicherung, BMBF, BMWi, NVIDIA Inception, and QCI. The firm operates from TechQuartier in Frankfurt with 1–10 employees under managing directors Markus C. Braun and Niklas Hegemann and CTO Thomas Decker, and is independently owned with no disclosed external funding.

JoS QUANTUM product offering
Product offeringCore offering
JoS QUANTUM develops quantum algorithms for real industrial use cases and provides consulting services spanning problem formulation, quantum circuit design, and hardware-resource estimation. The company specializes in quantum amplitude estimation for financial risk modeling, Shor's algorithm analysis for cryptographic assessment, and quantum key distribution (QKD) security proofs. Engagements scale from short keynotes (0.5-1 hours) to multi-month proofs of concept (3-24 months) for clients in finance, security, and energy sectors.
Product overview
JoS QUANTUM is a Frankfurt am Main-based quantum technology company offering a portfolio of quantum algorithm consulting and professional services — not a packaged software product. The core offering is quantum algorithm development (Problem → Formulation → Circuit → Hardware Estimate) targeted at industrial clients in quantitative finance, energy, and communications security. This service-based practice is complemented by a growing body of patented IP (quantum key distribution, ML-based quantum communication security proofs), published research (risk sensitivity analysis, portfolio optimisation, energy markets), and two interactive browser-based demos — RISQ (quantum risk analytics using amplitude estimation) and the RSA Break Estimator (Shor's algorithm resource estimation) — that serve as proof-of-concept demonstrations of their consulting capabilities. All offerings are grounded in published quantum algorithms and hardware-roadmap analysis.

Products and services
- Quantum Algorithm Development Services End-to-end quantum algorithm development for real industrial use cases, encompassing problem formulation, quantum circuit design, hardware-resource estimation (qubit counts, gate depth, error-correction overhead), and co-creation of IP and patents for clients in quantitative finance, energy, and security sectors.
- Training & Education Quantum computing fundamentals and algorithm literacy for technical teams and decision-makers, ranging from 0.5-1 hour high-level keynotes to 1-5 day hands-on workshops covering fundamentals through circuit development.
- Technical Due Diligence Independent technical assessment of quantum computing companies for investors and strategic partners, evaluating algorithmic feasibility, hardware requirements, and roadmaps.
- Strategy Advisory Independent advisory on quantum technology roadmaps, use-case prioritisation, investment timing, and vendor noise separation for enterprise and investor clients.
- RISQ — Quantum Risk Analytics Demo Interactive browser-based demo modelling business risk as a probabilistic network, compiling it to a quantum circuit, and estimating tail risk using quantum amplitude estimation — demonstrating quadratic speedup over classical Monte Carlo simulation.
- RSA Break Estimator — Shor's Algorithm Demo Interactive browser-based demo estimating quantum hardware resources (logical qubits, Toffoli gates, physical qubits) required to break RSA encryption for any key size, comparing surface-code (2019) and qLDPC (2026) error-correction schemes.

JoS QUANTUM competitors and assessment
Company assessmentDirect peers
- Multiverse Computing: Spain-based quantum software firm focused on quantum and quantum-inspired algorithms for finance (portfolio optimization, risk, derivatives pricing). Most direct comp to JoS Quantum: similar consultancy/SaaS blend, similar finance-vertical specialization, similar European roots, competing for the same Tier-1 European bank and insurance clients.
- QC Ware: Enterprise quantum software and algorithms company developing quantum algorithms for finance, chemistry, and machine learning. Competes head-to-head with JoS Quantum for quantum algorithm consulting engagements and serves a similar customer base of large financial and industrial enterprises.
- Zapata AI: Quantum + AI algorithms company (formerly Zapata Computing) building enterprise quantum software and optimization methods. Overlaps with JoS Quantum on quantum algorithm development services for industrial clients and offers competing product/consulting paths to similar finance and enterprise accounts.
- 1QBit: Quantum software company developing algorithms for optimization, simulation, and machine learning with enterprise customers in finance and resources. Similar professional-services-plus-IP positioning to JoS Quantum and known for finance-focused quantum work.
Broad incumbents
- Quantinuum: Large full-stack quantum company (Honeywell + Cambridge Quantum) offering trapped-ion hardware plus an algorithm/applications arm covering finance, chemistry and cryptography. Aboard the same quantum finance RFPs as JoS Quantum, but with vertical depth and captive hardware that gives it incumbent leverage in enterprise benchmarks.
- Xanadu: Photonic quantum hardware plus PennyLane software platform with finance and machine learning applications. Comparable on quantum algorithm development and finance use cases, though anchored to its own hardware and developer-tools stack.
Emerging players
- Classiq: Quantum software company building a high-level quantum algorithm development platform. Competes with JoS Quantum in quantum algorithm design and engineering services and serves overlapping financial services customers, but with a platform/productized approach rather than bespoke consulting.
- Strangeworks: Quantum computing software and services company offering a managed platform plus enterprise quantum consulting. Overlaps with JoS Quantum on the consulting/professional-services layer that helps enterprises adopt quantum algorithms, though focused on multi-vendor integration rather than algorithmic research.
- QunaSys: Quantum algorithms and software company with strong material/chemistry roots broadening into optimization and finance. Competes for quantum algorithm consulting engagements and shares the academic-research-to-industry pattern that defines JoS Quantum's GTM.
Regional players
- Terra Quantum: Swiss-headquartered quantum technology company offering quantum algorithms and products across finance, energy, and security. Most direct European peer to JoS Quantum by geography and vertical mix (finance + security + energy) but rarely competes head-to-head outside DACH given Switzerland's sovereign positioning.
