HQS Quantum Simulations supports QUANTITY in the investigation of new methods for quantum cryptanalysis

11. November 2024

We put out a call for tenders to find support for our quantum cryptanalysis project QUANTITY. HQS Quantum Simulations was awarded the contract.

What significance do quantum computers and quantum algorithms have for cryptanalysis? Our cryptanalysis project QUANTITY at the DLR Institute of Communications and Navigation is looking into this question – and has found competent support for it: through a cooperation with the German Federal Office for Information Security (BSI) and a research and development contract with HQS Quantum Simulations.

The Karlsruhe-based start-up HQS will support the QUANTITY team in analysing and adapting quantum algorithms and designing quantum computing software. Together with BSI as a cooperation partner, QUANTITY thus combines in-depth cryptographic and cryptanalytical expertise with a strong application and practical focus.



Practical relevance instead of abstraction

The analysis of the relevance of quantum algorithms for cryptanalysis should be oriented towards the practical application of quantum algorithms and not exclusively consider the abstract asymptotic scaling behaviour. This includes, for example, the resource overhead or the input sizes from which the algorithms can actually be used in practice. Due to the many possible combinations of cryptographic methods and quantum algorithms, QUANTITY is focussing on particularly promising approaches.
