SUR's modular photonic computer is now fully operational SUR's modular photonic computer is now fully operational ========================================================== CIVIS Highlights 26 January 2026 *Qolossus 2.0*, Italy's first modular photonic quantum computer, has been officially unveiled. It is the first Italian photonic quantum computer based on photons, the quanta of light, rather than superconducting circuits. The name honors *Colossus*, one of the earliest computers, renowned for decoding messages from the Enigma system. ![](https://civis.eu/storage/files/at-irene-scifoni-02-sapienza-quantum-lab-copia.jpg)© Irene Sofia Scifoni \_ Sapienza università di RomaQolossus2.0 is an innovative type of quantum computer that exploits the properties of light quanta. This approach allows the system to operate at room temperature and makes it naturally compatible with quantum communication networks, which also rely on photons to transmit information. In addition to standard qubits, the platform can process higher-dimensional quantum units, known as *qudits*, enabling a more efficient encoding of information and opening new perspectives for quantum algorithms and applications. The core processor consists of integrated photonic circuits fabricated in Italy using advanced laser- based nanofabrication techniques, while quantum light sources are generated on dedicated chips and connected via optical fibers. > *Research is the most authoritative language that Italy and Europe can speak in the world, and it is a language based on verifiable results, transparent processes and our country's unique ability to combine scientific tradition, cultural vision and civic responsibility",* emphasises Sapienza Rector Antonella Polimeni. Qolossus 2.0 is a significant step forward in the development of an alternative type of quantum computer based on photons as computing units. It was developed as part of the National Research Centre for High Performance Computing, Big Data and Quantum Computing initiative (PNRR ICSC), coordinated by Sapienza University of Rome at the [Quantum Lab](https://www.quantumlab.it/). ![](https://civis.eu/storage/files/at-irene-scifoni-04-team-at-the-presentation-copia.jpg)© Irene Sofia Scifoni \_ Sapienza università di RomaContributions also came from research groups at the Institute of Photonics and Nanotechnology of the National Research Council in Milan, and the University of Pavia. **Find out more from the** [**original story, in Italian**](https://www.uniroma1.it/it/notizia/presentato-qolossus-20-il-quantum-computer-fotonico-italiano-modulare-della-sapienza)**.** Related news ------------ - [ ![](https://civis.eu/storage/files/02-mlk-foto-di-stefania-sepulcri_2-800x600.jpg?token=5ce00b0649bc049397348a1e5df68500)An in-depth exhibition at Sapienza celebrating Martin Luther King - the icon of the Civil Rights Movement CIVIS Highlights 2 December 2025 ](https://civis.eu/en/the-civis-newsroom/an-in-depth-exhibition-at-sapienza-celebrating-martin-luther-king-the-icon-of-the-civil-rights-movement) - [ ![](https://civis.eu/storage/files/scalone-at-stefano-segati-800x600.jpg?token=734ed2f975bbbae331b190d46e57f25e)90 Years of Sapienza Main Campus: a celebration of renewal and solidarity CIVIS Highlights 22 October 2025 ](https://civis.eu/en/the-civis-newsroom/90-years-of-sapienza-main-campus-a-celebration-of-renewal-and-solidarity) - [ ![](https://civis.eu/storage/files/labs-persone-800x600.jpg?token=bf60f8bb63614804d0ac452e9df043ea)SUR researchers identify key elements for food safety and quality CIVIS Highlights 8 September 2025 ](https://civis.eu/en/the-civis-newsroom/sur-researchers-identify-key-elements-for-food-safety-and-quality) [Discover all our stories](https://civis.eu/en/the-civis-newsroom) [ Litter in the Rhine River: some 53,000 items of litter flow past Cologne daily ](< https://civis.eu/en/the-civis-newsroom/litter-in-the-rhine-river-some-53-000-items-of-litter-flow-past-cologne-daily >) [ Doctoral Webinar Challenges of Digital and Technological Transformations is back ](< https://civis.eu/en/the-civis-newsroom/doctoral-webinar-challenges-of-digital-and-technological-transformations-is-back >) ![CIVIS – Europe’s Civic University Alliance](https://civis.eu/build/assets/civis-CCpvK1nT.svg) ------------------------------------------------------------------------------------------------- Europe’s Civic University Alliance ![Co-funded by the European Union](https://civis.eu/build/assets/co-funded-by-the-european-union-DSKLW1us.png)Views and opinions expressed do not necessarily reflect those of the European Union or the European Education and Culture Executive Agency (EACEA).
