PRESS RELEASE — The QLASS project, focused on advancing Quantum Photonic Integrated Circuits (QPICs), has secured €6 million (approximately $6.5 million) in funding from the European Commission. The initiative is led by a consortium coordinated by Politecnico di Milano, and includes the following partners: CNRS-Institut Charles Gerhardt Montpellier, Ephos, Fondazione Politecnico di Milano, Pixel Photonics, Quantum Lab in Sapienza Università di Roma, Schott AG, Unitary Fund France, and Université de Montpellier.

QPICs are specialized devices that leverage the properties of light and quantum mechanics to execute complex tasks in fields such as quantum computing, communication, and sensing. By integrating multiple photonic components, such as waveguides, beam splitters and detectors, into a single chip, QPICs offer a scalable solution for manipulating quantum states of light with high precision. These circuits hold the potential to significantly reduce the size, cost, and complexity of quantum systems, paving the way for real-world applications.

However, the development of QPICs is currently limited by challenges such as photon loss, scalability issues, fabrication complexity, and imperfect photon sources. The QLASS project tackles these challenges heads on.

To address the limitations of current QPIC technology, QLASS will employ femtosecond laser writing to fabricate 3D waveguides within glass specifically developed for optimal photonic performance, significantly reducing losses. Additionally, the project will incorporate high-performance single-photon sources, superconducting nanowire single-photon detectors (SNSPDs), and advanced electronics capable of programming the whole system. Lastly, the team will develop software to compile quantum programs onto the special QPIC processors.

A principal use case of the QLASS project is modeling complex systems and materials. In particular, QLASS will pave the way to the design of new materials and technologies for lithium-ion batteries, aiming to improve their capacity, efficiency and cyclability which are crucial in meeting the European Union’s technological and sustainability goals.

QLASS will bring significant advancements to the development of QPIC technology and also contribute to progress in glass development and novel SNSPD processes. These breakthroughs are expected to benefit the broader quantum technology community and enable new quantum devices with performance levels far beyond the current platforms.

“The QLASS project holds the potential for establishing a new path in quantum computing research,” said Dr. Giulia Acconcia from Politecnico di Milano, the QLASS Coordinator. “By exploiting various technologies, each one specifically developed to optimize one aspect of quantum processing, and yet pursuing a high level of integration, QLASS will show a viable approach to achieving extremely high performance in a compact scalable circuit.” “QLASS’ synergy between platform and algorithms development” – added Acconcia – “can affect both the research and the market in many application areas, such as quantum information and metrology.”
