Quantum Computing Meets High Performance Computing

In addition to the hardware implementation of quantum computers, the development of suitable software is a key challenge for the future use of this promising technology. In the division »Analytics and Computing«, we develop new quantum algorithms and software solutions, optimize them for specific problems, and test them in practical applications. In interdisciplinary teams from mathematics, computer science, and physics, we work on current issues in our business areas and, in particular, investigate the interaction between classical high-performance computers and quantum computers.

One focus is on benchmarking, software integration, and hybrid applications that combine classical and quantum-based computing methods. Hybrid algorithms, in which classical and quantum components work closely together, play an important role, especially in the NISQ era and the early FTQC era. Particular attention is paid to applications from quantum chemistry, which are considered early candidates for quantum advantage and combine classical expertise with quantum extensions.

In addition, we are developing central components of the software stack for operating quantum computers, in particular quantum compilers that efficiently map abstract quantum programs to real hardware. The goal is to minimize compilation overhead and achieve technological advantages for our algorithms. Through partnerships with quantum hardware providers, we have access to various hardware architectures in Europe and around the world, particularly to a quantum computer located in Germany that is operated by IBM in compliance with German data protection laws.
