The QLASS project, led by Politecnico di Milano, is working to develop a quantum photonic computer that harnesses the quantum properties of photons-the fundamental particles of light. With a euro 6 million grant from the European Union as part of the “Quantum Flagship” initiative, the three-year project aims to advance quantum computing capabilities for practical applications.
Quantum computers utilize the principles of quantum mechanics to solve complex problems much faster than traditional computing systems. Some computational tasks-such as drug discovery-that would take millions of years on even the most powerful conventional supercomputers could potentially be completed in minutes by a quantum computer.
Currently, no quantum computer is sufficiently large or precise to tackle industrial-scale challenges. However, a worldwide initiative involving governments, universities, startups, and major technology firms is dedicated to making such a system a reality.
“The QLASS project will make an important contribution to the development of versatile modular components that can be widely used in industry and research, as well as to training a new generation of quantum technology experts,” said Giulia Acconcia, coordinator of the QLASS project.
A key focus of QLASS is the creation of new algorithms designed to leverage the unique advantages of quantum photonic processors. To illustrate the capabilities of this innovative technology, researchers will employ the quantum photonic computer in the design of high-capacity, efficient lithium batteries.
The challenge of developing lithium batteries that are smaller, lighter, faster to charge, and longer-lasting is a demanding one. Quantum computing could offer solutions that significantly enhance battery performance compared to conventional computational methods. Given their widespread use in everything from smartphones to electric vehicles and bicycles, advancements in battery technology are increasingly crucial.
The QLASS consortium consists of experts from both academia and industry across Europe. The participating institutions include Centre National de la Recherche Scientifique, Ephos, Fondazione Politecnico di Milano, Pixel Photonics, Sapienza University of Rome, Schott AG, Unitary Fund France, and Universite de Montpellier.
