From optimizing traffic management and forecasting energy consumption to improving urban logistics, reducing environmental impact, and ensuring secure data management, future cities will overcome key challenges by integrating quantum technologies into their infrastructures. Leading this transformation is CRS4 \u2013 the Center for Research, Development and Advanced Studies in Sardinia \u2013 a key player in the DLAB | Cagliari Digital Lab project, an initiative promoted by the Ministry of Enterprises and Made in Italy, and Invitalia, with the Municipality of Cagliari as the lead partner.<\/p>\n
“Through our contribution to the project, CRS4,” explains Giacomo Cao, the sole administrator of the Center, “is engaged in research and development to optimize essential urban services\u2014such as waste collection and local public transportation\u2014using quantum computing. In addition, CRS4 coordinates the Quantum Technologies Laboratory, a hub dedicated to communication, numerical and hybrid computing, aimed at accelerating the adoption of these technologies in practical applications.”<\/p>\n
Quantum Computing is a paradigm based on quantum mechanics. Unlike traditional computers that use classical bits (0 or 1), quantum computers leverage qubits<\/em>\u2014units of information that can exist in multiple states simultaneously thanks to superposition. Combined with entanglement, this allows them to perform extremely complex calculations in dramatically reduced time. “Quantum Computing,” emphasizes Giacomo Cao, “is a revolutionary technology with applications ranging from cryptography to computational chemistry, solving numerous optimization challenges and even advancing artificial intelligence.”<\/p>\n Smart cities built on advanced technologies offer multiple benefits. “First of all, urban mobility is optimized,” explains Giuliana Siddi Moreau, a CRS4 researcher specializing in quantum technologies. “Advanced data analysis and quantum computing algorithms can reduce traffic, improve road usability, and optimize public transportation. Additionally, intelligent waste management systems employing advanced collection and disposal methods can lower environmental impact and enhance logistical efficiency.” She adds that energy savings can be achieved through monitoring and forecasting consumption with artificial intelligence, enabling better energy distribution and promoting renewable sources. “Moreover, quantum communication enables the development of advanced encryption systems to protect citizens\u2019 sensitive data. Predictive analytics further allow the design of more resilient and sustainable infrastructures, reducing waste and improving quality of life,” notes Lidia Leoni, head of the Quantum and High-Performance Computing, Biosciences and Advanced Studies sector at CRS4.<\/p>\n Quantum computing also has the potential to revolutionize sustainable energy research. “Quantum computers could simulate new substances and materials that enhance the efficiency of batteries or solar panels,” says Giacomo Cao. “This could lead to longer-lasting, more efficient energy devices, reduce reliance on fossil fuels, and improve energy sustainability. Research on room-temperature superconductors, for instance, could be accelerated by quantum computing, paving the way for advanced energy technologies like lossless electrical grids and more powerful, efficient motors.”<\/p>\n Within the DLAB project, CRS4 is involved in four key activities:<\/p>\nInnovation and Sustainability for Smart Cities<\/h2>\n
