Scientists at Paderborn University have achieved a major milestone by using high-performance computing to analyze a quantum photonics experiment on a large scale for the first time. This breakthrough involved utilizing the Paderborn supercomputer Noctua to perform complex calculations extremely quickly, enabling new methods in quantum experiments and high-performance computing. The research team developed innovative HPC software to carry out the tomographic reconstruction of experimental data from a quantum detector, a device that measures individual photons or light particles.
Traditional approaches have struggled to handle the enormous volumes of data involved in effectively characterizing these high-resolution photon detectors due to the quantum mechanical structure of the data sets at such a large scale. Physicist Timon Schapeler, along with computer scientist Dr. Robert Schade and colleagues from PhoQS (Institute for Photonic Quantum Systems) and PC2 (Paderborn Center for Parallel Computing), authored the pivotal paper published in the journal Quantum Science and Technology.
HPC innovation in quantum analysis
Schapeler explained, “By developing open-source customized algorithms using HPC, we perform quantum tomography on a megascale quantum photonic detector.”
The team’s findings are opening up new horizons for the size of systems being analyzed in the field of scalable quantum photonics, with wider implications for characterizing photonic quantum computer hardware. Remarkably, their system performed calculations that describe a photon detector in mere minutes, far outpacing previous capabilities and demonstrating the unprecedented scale at which this tool can be utilized in quantum photonic systems.
Schapeler emphasized the importance of their work in demonstrating quantum supremacy in quantum photonic experiments, which operate beyond the computational capacity of conventional tools. He is a doctoral student in the “Mesoscopic Quantum Optics” research group led by Professor Tim Bartley, which focuses on the fundamental physics of quantum states of light and their applications, comprising states of tens, hundreds, or thousands of photons. Professor Bartley highlighted the significance of scale, stating, “The scale is crucial, as this illustrates the fundamental advantage that quantum systems hold over conventional ones.
There is a clear benefit in many areas including measurement technology, data processing, and communications.”
The careful application of high-performance computing in these experiments marks a significant step forward in both experimental and computational physics, ultimately contributing to a deeper understanding of the underlying principles of quantum mechanics. Quantum research is a flagship field at Paderborn University, where esteemed experts are conducting fundamental research to shape the future’s specific applications.
