Quantum Physics Breakthrough: Photons Exist in 37 Dimensions, Italian Quantum Backbone Expands

Recent breakthroughs in quantum physics are challenging classical concepts, revealing the non-classical behavior of subatomic particles. In China, scientists conducted an experiment confirming the Greenberger-Horne-Zeilinger (GHZ) paradox, demonstrating that photons can exist in 37 dimensions. This high-dimensionality offers robustness against noise and errors, benefiting areas like algorithm creation, quantum information transmission, quantum computing, and advanced sensors. Such advancements may lead to the development of novel technologies. In Italy, the Italian Quantum Backbone (IQB) is expanding, with a new operational headquarters of the National Institute of Metrological Research (Inrim) in Sesto Fiorentino. This infrastructure distributes time signals across the country using fiber optics. The new center focuses on quantum computing using ions and advanced materials for quantum technologies. Two projects funded by the European Research Council (ERC) are underway, exploring soft materials like polymers for secure information storage readable with optical techniques. Measurement science is crucial for analyzing and certifying the performance of these cutting-edge technologies.
