Congrats to our own Ashwin Jans and team members for winning the Nostics challenge at the PIC Hackathon!
The 2nd International PIC Hackathon has officially concluded, marking the end of an inspiring and impactful programme that brought together students, academia, and industry from around the world to explore the future of Integrated Photonics. The week featured expert lectures, company visits, lab tours, and challenging student projects, all culminating in the final presentations, where participants shared their innovative solutions to challenges set by Nostics and Dexerials Corporation. The winning teams were recognised during a special ceremony at Expo 2025 Osaka, with awards presented by Sawaragi, Executive Vice-President of Kyoto University, and Feite Hofman, Vice Minister of Education, Culture and Science of the Netherlands. We extend our congratulations to: 🏆 Ashwin Jans, Bart Bas, and Ryoichiro Sahara – winners of the Nostics challenge 🏆 Lyuben Davidov, Ronak S. Emami, and Sakutaro Nogi – winners of the Dexerials Corporation challenge. It was an honour to be part of this international collaboration and to be welcomed at Expo 2025 Osaka by Gilles Beschoor Plug, Dutch Ambassador to Japan. PhotonDelta thanks all partners – Nostics, Dexerials Corporation, Casimir Institute, Kyoto University, University of Twente and Expo 2025 Osaka for supporting an initiative that offers students a unique view into the exciting world of Integrated Photonics. Special thanks goes out to Marc Kuipers, Consul-general for the Kingdom of the Netherlands in Osaka, Susumu Noda, distinguished professor at Kyoto University, and Ina Adema, King’s Commissioner (provincial governor in the Netherlands) of Noord-Brabant. We are proud of the innovation, creativity, and collaboration this hackathon inspired - and look forward to the next edition.
Highly recommended! Chaired by AQO's Pepijn Pinkse, there's a nice session on Integrated Quantum Photonics with Philippe Bouyer from Eindhoven University of Technology, Gillen Beck from ETH Zürich and Daan Stellinga from QSA Technology as speakers.

Check out this paper from Frank Somhorst, Jason Saied, Eleanor Rieffel and Jelmer Renema. This work was done together with NASA - National Aeronautics and Space Administration
Thought you knew everything there is to know about two-photon (HOM) interference and how to use it to measure photon quality? Well, turns out you were wrong! There's a subtle little interaction between multiphoton errors and indistinguishability errors that can mess up your measurements if you're not careful. In this paper, we show how to disentangle the two. https://lnkd.in/e3TD2BDZ

🎲 Quantum Monte Carlo on Alquor® Monte Carlo methods are a cornerstone of modern science, used everywhere from finance to chemistry. Now, the Adaptive Quantum Optics group at the University of Twente has shown how these powerful techniques can run on our Alquor® #QuantumPhotonicProcessor. Building on boson sampling, the team implemented a sampling-based Monte Carlo approach that is naturally suited to photonics. They applied it to a quantum chemistry problem, showing how photonic quantum computing can tackle meaningful scientific challenges even in the near term. 👉 Read the paper: https://lnkd.in/eeTs7B9Q We are proud to see Alquor® enabling yet another research that moves quantum photonics beyond theoretical discussions and toward real-world applications. #QuantumComputing #QuantumMonteCarlo #Alquor #QuantumChemistry #PhotonicQuantumComputing

Check out this paper by Malaquias Correa Anguita, Teun Roelink, Sara Marzban, Wim Briels, Claudia Filippi, and Jelmer Renema on boson sampling for quantum chemistry!
Do near-term quantum computers have use cases? This question has been central to the field since the first quantum advantage demonstrations. In photonics specifically, progress has been held back by poor considerations of the sampling aspects of quantum advantage systems: boson samplers neither have a quantum advantage for computing permanents nor for the arrival probability of single photons. These two facts have sunk (depending on who you ask) all or almost all previous proposals for use cases. We experimentally implement a use case for photonics that natively uses samples, thereby sidestepping these problems. We implement this use case for a specific problem in quantum chemistry. https://lnkd.in/eEs7_2z2

It was an honour and a pleasure to give a keynote at PhotonicsNL's Dutch Photonics Event last week at Saxion University of Applied Sciences. I could entertain the diverse audience of Dutch photonics industry and academics with a talk about quantum photonics in Twente, exemplified by spinouts of the University of Twente: LioniX International, QuiX Quantum (further illustrated by my colleague Jelmer Renema), and QSA Technology. I had the feeling that the Quantum dice from Aernout van Rossum made a face-on impression 😀. Thanks to Steven van den Berg and Petra Wicherink for the invite and Daniela Godoy for all the support!
