In a remarkable leap forward for quantum photonics and computational physics, researchers at the Institute for Photonic Quantum Systems (PhoQS) and the Paderborn Center for Parallel Computing (PC2) at Paderborn University have unveiled a cutting-edge, open-source software tool named “Phoenix.” This powerful new platform enables scientists worldwide to simulate the intricate behavior of light within quantum systems with unprecedented speed and detail, all while eliminating the barrier of expertise in high-performance computing. The outcomes of this pioneering project have been published in the prestigious journal Computer Physics Communications, heralding a transformative resource for researchers striving to decode the quantum frontier.
Phoenix is fundamentally designed to solve complex nonlinear partial differential equations that govern quantum light-matter interactions, specifically focusing on the nonlinear Schrödinger and Gross-Pitaevskii equations in two spatial dimensions. These equations are central to modeling phenomena where light and matter interplay in highly non-classical regimes, contributing critically to advancements in quantum technologies, including quantum computing architectures and innovative photonic devices. According to Professor Stefan Schumacher, a leading physicist at PhoQS, Phoenix’s robust and flexible architecture is optimized to operate efficiently on a broad spectrum of hardware platforms — from conventional laptops to high-performance GPUs — boasting execution speeds up to a thousand times faster than traditional computational tools, with energy efficiency improved by as much as 99.8 percent.
One of the distinctive features of Phoenix is its accessibility. As open-source software, it empowers the global scientific community with a state-of-the-art computational instrument previously constrained to highly specialized teams with access to expensive supercomputing resources. This democratization of computational power is anticipated to accelerate discoveries across photonics, quantum communication, and information processing, particularly by facilitating rapid prototyping and detailed investigations of complex quantum states of light without necessitating deep expertise in HPC (High Performance Computing) infrastructures.

The genesis of Phoenix’s extraordinary performance stems from an interdisciplinary collaboration between physicists and HPC specialists at PC2, which is known for its leadership in computational science and world-class infrastructure. PhD student Jan Wingenbach, the lead author of the pivotal study detailing Phoenix, emphasized that the software’s optimization relied extensively on this synergy, highlighting the critical role of cross-domain cooperation in overcoming computational bottlenecks that have historically limited progress in quantum photonics simulations.
Paderborn University’s HPC credentials are particularly noteworthy. The institution is a key node within the German National High-Performance Computing (NHR) Alliance, providing computational resources to researchers across the country. The recent deployment of the “Otus” supercomputer — which earned fifth place globally on the Green500 list for energy-efficient computing — reflects Paderborn’s commitment to sustainable and powerful computing solutions. Phoenix leverages such infrastructure, ensuring the software is not only fast and accurate but also environmentally responsible.
The impact of Phoenix extends beyond theoretical modeling, as exemplified by its applications in recent experimental collaborations. Previous versions of the software contributed significantly to studies involving optically controllable photonic bits within quantum fluids composed of hybrid light-matter quasi-particles known as polaritons. In these experiments, researchers achieved controlled switching of optical vortices, a phenomenon integral to photonic quantum information schemes. These investigations were carried out in partnership with TU Dortmund as part of the Collaborative Research Centre/TRR142, showing how Phoenix bridges computational theory and cutting-edge experimental physics.
Furthermore, Phoenix has enabled fundamental studies on macroscopic analogues of qubits, investigations into split-ring polariton condensates as two-level quantum systems, and explorations of quantum coherence in polariton condensates. These pursuits include time-resolved tomography techniques capable of capturing ultrafast quantum states of condensed matter systems, delineating new paths for quantum state control and measurement. These studies cement Phoenix’s role as a foundational tool for probing complex many-body quantum phenomena with high temporal and spatial resolution.
Looking ahead, the full public release of Phoenix anticipates a significant expansion of these research areas, especially quantum information processing and hybrid photon-matter quantum systems. By facilitating the simulation of non-linear quantum optical phenomena with high fidelity and efficiency, Phoenix empowers scientists to iteratively design, predict, and refine quantum devices and protocols that could underpin next-generation computing and communication technologies.
The philosophy behind Phoenix underscores the importance of interdisciplinary convergence: merging quantum physics, computational mathematics, computer science, and electrical engineering. Such collaboration has already yielded tangible technological milestones, including the establishment of Germany’s first light-based quantum computer, PaQS, which commenced operations in Paderborn last year. This synergy exemplifies how combined expertise in algorithm development, hardware optimization, and quantum theory can push the frontiers of what is computationally achievable.
Dr. Robert Schade, an HPC specialist integral to the Phoenix project, highlighted the broader implications of this synergy in extending the boundaries of computing power and capability. As Phoenix continues to mature, it is poised to become an indispensable computational engine fueling breakthroughs across a spectrum of photonics and quantum science disciplines. It promises to accelerate discovery cycles by enabling researchers to test hypotheses and explore photon interactions within complex quantum states that were previously inaccessible due to computational constraints.
Phoenix’s debut has already sparked international recognition. Jan Wingenbach recently presented the project at the OECS19 Conference in Warsaw, where his poster was honored with the Best Poster Award, underscoring the scientific community’s enthusiasm for this advanced modeling tool. Its open-access release stands to catalyze a paradigm shift in how quantum photonics research is conducted globally, facilitating collaborations and innovations that harness the full complexity of light at quantum scales.
In conclusion, Phoenix is not just software — it is an open gateway to the next era of quantum photonics research, breaking computational barriers and setting new standards for the simulation of quantum light-matter interactions. By making powerful, efficient, and user-friendly quantum simulation tools universally available, PhoQS and PC2 have established a transformative platform that aligns scientific rigor and technological innovation. This initiative dramatically accelerates the exploration of complex quantum phenomena, bringing us closer to the practical realization of quantum computers and advanced photonic technologies.
