In an interview with the UN Chronicle, Professor Dr. Klaus Richter, President of the Deutsche Physikalische Gesellschaft, discusses the significance of quantum physics in light of the International Year of Quantum Science and Technology (IYQ) 2025. He explains that quantum mechanics bridges gaps in classical physics, enabling a deeper understanding of the universe from atomic interactions to technological advancements like transistors and medical imaging. Dr. Richter highlights the emergence of a “second quantum revolution,” promising innovations in quantum computing and sensor technology. He also emphasizes the intertwining of quantum physics with artificial intelligence and data science while calling for responsible development and transparency regarding the societal impacts of these technologies. As part of IYQ, a year dedicated to celebrating the legacy of quantum science, the DPG will host numerous events to foster international collaboration and inspire future generations in the field.
