Phoenix: Paderborn University Releases Revolutionary Open-Source Quantum Physics Software, Transforming Light-Matter Simulations
‘Phoenix’ is a sophisticated and innovative open-source software tool that scientists from Paderborn University have presented. It is expected to greatly speed up quantum physics research and the creation of future quantum technology.
Phoenix, which was created by specialists from the Paderborn Centre for Parallel Computing (PC2) and the Institute for Photonic Quantum Systems (PhoQS), allows researchers to simulate light behavior in quantum systems with previously unheard-of speed and detail and importantly, without requiring a deep understanding of high-performance computing (HPC). The prestigious journal Computer Physics Communications has formally published the outstanding outcomes of this development.

Phoenix is specifically made to solve intricate equations that mathematically explain the quantum interactions between light and matter. Gaining a thorough grasp of basic quantum phenomena and designing and developing cutting-edge technologies, such as future quantum computers and sophisticated photonic devices, depend heavily on this capacity. “More specifically, we are looking here at so-called non-linear Schrödinger and Gross-Pitaevskii equations in two spatial dimensions,” explained Professor Stefan Schumacher of PhoQS, who provided further details on the software’s specific uses.
Phoenix’s exceptional accessibility and efficiency are two of its most notable assets. Because of its creative design, Phoenix can function well on regular laptops or high-performance Graphics Processing Units (GPUs), in contrast to many traditional tools that require specialized hardware or extensive HPC knowledge. Professor Schumacher emphasized its remarkable performance, pointing out that it can outperform current conventional methods by up to a thousand times and has an energy efficiency of up to 99.8%.

Additionally, Phoenix has been made freely available to scholars worldwide as an open-source tool in an effort to promote broad adoption and cooperative advancement among the international scientific community. The program is easily accessible to researchers directly through GitHub. Scientists can now better comprehend and monitor light at the smallest scales with the software, which is already being used to investigate novel physical processes within rare quantum states of light.
Experts in advanced quantum photonics and High-Performance Computing worked closely together and synergistically to bring Phoenix to its current, highly optimized state. “Optimization to the current level was only possible through the close cooperation with the HPC experts from PC2,” said Jan Wingenbach, the study’s principal author and a PhD candidate, confirming this important partnership. The significant influence of this collaboration was further highlighted by Dr. Robert Schade, a research assistant and HPC specialist at PC2, who said, “This synergy between cutting-edge research in quantum photonics and high-performance computing has made it possible for us to extend the limits of computing power and capability.”
With PC2 as a primary area of study, Paderborn University is well known for its extensive knowledge of HPC. The institution has a long history and pertinent expertise in the field of computational science, and it provides top-notch, cutting-edge facilities. Through the NHR Alliance, a large amount of its computing capacity is also made available to researchers throughout Germany. The university’s new supercomputer, ‘Otus,’ recently secured an impressive fifth position in the ‘Green 500’ list of the world’s most energy-efficient computing systems at the ISC in Hamburg, an international trade show for high-performance computing, artificial intelligence, data analytics, and quantum computing. This achievement highlights the university’s steadfast dedication to advanced computing.

At the same time, PhoQS stands out as a world leader in quantum and photonics research. Supported by an interdisciplinary team of professionals from Physics, Mathematics, Computer Science, and Electrical Engineering, it performs outstanding work in the vital fields of quantum simulation, communication, metrology, and computing. Germany’s first light-based quantum computer, PaQS, also started operations in Paderborn last year, further solidifying Paderborn’s leadership in quantum technology.
Important advances in quantum photonics have already been made possible by early iterations of the Phoenix code. Among its noteworthy prior contributions are:
- Simulating optically controlled photonic components in a quantum fluid made up of particles that combine matter and light. In cooperation with TU Dortmund as part of the Collaborative Research Centre/TRR142, a controlled switching of optical vortices was successfully demonstrated in this study.
- Aiding basic research on qubits, the fundamental building blocks of quantum information, and their macroscopic counterparts.
- Examining split-ring polariton condensates as quantum systems with two levels.
Ultra-fast, time-resolved tomography of quantum states in complicated condensed systems was made possible by research on quantum coherence in polariton condensates. As part of TRR142, this was also done in collaboration with TU Dortmund.

According to the team, Phoenix will develop into a vital computational tool for next studies on novel photonic states and how they interact. It is anticipated that Phoenix’s entire publication would greatly build on these earlier investigations. It is anticipated to be extremely important for the ongoing development of PhoQS research, notably in the fields of hybrid photon-matter-quantum systems and quantum information processing. Its open-access nature is expected to promote broad advancement in a variety of fields, including quantum computing and non-linear optics.
