A collaboration of scientists from Italy, Germany, and France is focused on developing a new generation of quantum computers utilizing glass photon chips.
These devices, which have the potential to surpass traditional computers, face numerous challenges in their realization. The initiative, led by the Polytechnic University of Milan, brings together experts from leading research institutions and small enterprises aiming to enhance quantum technologies using the unique properties of glass.
The researchers are implementing chips developed by Ephos to create photon quantum computers. These chips are capable of processing information using light, supporting up to 200 optical modes, allowing for dynamic control of light movement.
«Utilizing transparent materials presents a complex challenge, as it is essential to confine light without allowing it to be absorbed. When light is absorbed, its propagation becomes impossible,» explains Julia Acconcia from the Polytechnic University of Milan.
The scientists aim to generate individual photons and guide them through glass circuits, which could potentially address pressing issues such as the development of new medicines and more efficient batteries. The laser printing technology on glass appears promising: light particles generated in the process enter the chip via optical fibers, minimizing the risk of photon deviation.
Currently, the company Pixel Photonics is working on enhancing sensitive detectors to register individual photons, while Schott AG supplies high-quality glass substrates.
The team led by Julia Acconcia is also developing electronics to manage the system, while experts from the University of La Sapienza are engaged in single-photon generation.
The French Single Fund is developing open-source software for quantum computing, while the National Center for Scientific Research and the University of Montpellier are modeling energy storage solutions, which are crucial for future quantum technologies.
The QLASS researchers share a common goal: to create a functional photon quantum device at the University of La Sapienza by 2026. After the project's completion, software developed at the University of Montpellier will enable testing of this device.
The first task for the new quantum computer will be the development of advanced lithium-ion batteries. By employing variational quantum algorithms, quantum computations can model battery chemistry, simplifying the search for new materials and improving their monitoring.
While scientists understand the laws governing atoms and compounds, tracking their interactions in real-time remains a complex challenge that exceeds the capabilities of modern silicon computers. Researchers hope that quantum computers will expedite the development of new materials for batteries and medicines.
The research findings are published in Horizon Magazine.
