London – The scientific article "Programmable microwave cluster states via Josephson metamaterials," produced through a collaboration between the University of Palermo, the National Institute of Metrological Research (INRiM), and the Polytechnic University of Turin, has been published in the prestigious international journal Nature Communications. Among the authors are Prof. Patrizia Livreri, Professor of Electronics, and PhD student Bernardo Galvano from the Department of Engineering at UniPa, both working on Josephson Traveling-Wave Parametric Amplifiers (JTWPA) to advance future quantum technologies. The research presents an innovative approach to the programmable generation of microwave quantum states using superconducting devices based on Josephson junctions. The findings demonstrate that these devices can serve not only as ultra-low-noise amplifiers, but also as tools for generating and manipulating complex quantum states—a critical resource for next-generation quantum computing architectures. This study marks a major leap forward toward increasingly scalable, reconfigurable quantum platforms that are fully compatible with the superconducting circuits used in cutting-edge quantum computers.
