PROJECTS
quSAA
Quantum computing for strategic asset allocation. The project investigates application of quantum algorithms to achieve lower fluctuations of investment portfolios to contribute to the stabilization of companies and thus of the financial system. The project is funded by the Federal Ministry of Education and Research (BMBF)
EnerQuant
Within this project we develop solutions for models in energy markets that consist of complex optimization problems including stochastic componentes. Solutions are prototyped and tested on various quantum hardware. The project is funded by the Federal Ministry for Economic Affairs and Energy.
DZ BANK AG TrendLab
Workshop to explore quantum computing, providing knowledge-transfer and use case identification for various applications in risk management, optimization and machine learning.
Asset Allocation
Jupyter notebook that translates the combinatorial optimization into a QUBO which can be solved by adiabatic quantum computing, gate-based algorithms and quantum-inspired algorithms. It shows how to allocate a long-short portfolio that minimizes overall risk based on covariance of assets.
A Quantum Algorithm for the Sensitivity Analysis of Business Risks
We present a novel use case for quantum computation: the sensitivity analysis for a risk model used at Deutsche Börse Group. Such an analysis is computationally too expensive to perform on classical computers.

TEAM
Markus C. Braun
Founder & Managing Director
Markus founded JoS QUANTUM in 2018. Before that, he worked for Deutsche Bank and as a consultant for various financial institutions. He advised and implemented various quantitative models for fraud detection and risk modelling. Markus studied mathematical physics in Magdeburg, Tokyo and Taipei.
Niklas Hegemann
Managing Director
Niklas is managing director of JoS QUANTUM. Before that, he worked as a management consultant in different business and technical areas focusing on software integration and financial services. He was responsible for several big projects mostly in the field of trading and risk management. Niklas worked at the German electron-synchrotron DESY where he used Monte Carlo simulation methods to validate high energy experiments. He received his degree (Dipl.-Phys.) with subsidiary subject economics in 2011 from University of Hamburg.
Sven Kerstan
Head of Research
Sven joined JoS QUANTUM in 2019. He has more than ten years of experience in trading and risk management. Most of that time he spent on the trading floor of a large proprietary trading company where, as Head of Research, he was in charge of all quantitative models and algorithms for trading and built up and managed a team of quants. Before that, he did Part III maths at the University of Cambridge, a PhD in theoretical physics at King’s College, London, and a postdoc at the Center for Theoretical Physics in Groningen.
Thomas Decker
Chief Technology Officer
Thomas joined JoS QUANTUM in 2019. Before he worked as a software developer for a high-performance database company where he was responsible for the optimization algorithms. He held postdoctoral research positions at the University of Washington in Seattle, at McGill University in Montreal and at the Centre for Quantum Technologies in Singapore. His research is focused on the design and analysis of quantum algorithms and on quantum information theory. He received his Diplom degree in computer science in 2002 and his Dr.rer.nat. degree with specialization in quantum algorithms in 2006 from the University of Karlsruhe (KIT).
