In the news
- A special moment in New York yesterday as Christophe Jurczak and Olivier Tonneau joined the Pasqal team at Nasdaq to ring the Closing Bell and celebrate the company’s listing. For Quantonation, this milestone has particular meaning as we backed Pasqal from the start. We led its seed round and later co-led its Series A, because we believed that extraordinary science could become an extraordinary company. Pasqal has grown from its roots in the French #quantum ecosystem into a global company, deploying quantum systems worldwide,
- Quantum Matter by Design. From 28–30 September, the third Alain Aspect Symposium will bring together researchers, founders, industry leaders and investors in Sherbrooke, Québec, to explore how advances in #quantum materials are moving from fundamental science towards real-world applications. Under the patronage of Nobel laureate alain aspect, this year’s programme spans quantum materials simulation, fabrication, industrial applications, quantum sensing, and the emerging intersection of quantum, HPC and #AI. Quantonation
- On Oct. 1, our Co-Founder and Partner Olivier Tonneau will join Georges-Olivier REYMOND of Pasqal and senior leaders from across Europe for the Luxembourg Quantum Alliance’s Leadership Lunch at the European Investment Bank (EIB). The discussion comes at an important moment. Pasqal’s recent Nasdaq listing showed what can happen when world-class European science is matched with ambitious entrepreneurship and long-term capital. The challenge now is to build many more companies capable of following that path. #Quantum #DeepTech #VC
- Taiwan has spent decades building one of the world’s most important technology ecosystems. Now, interest in #quantum is gathering momentum too. Last week, the Quantonation team was in Taiwan to see that progress first hand. A big thank you to Ching-Ray Chang, Joann Chu and TAQCIT for inviting us to take part in Quantum Investment Day on September 3, as part of Quantum Taiwan Forum 2026. Olivier Tonneau presented our approach to investing in and supporting quantum companies globally, alongside conversations with investors,
- Quantum is a global business which makes it all the better when you can get everyone in the same room. A few photos from a great evening in Singapore 🇸🇬, where the Quantonation team caught up with founders, researchers, investors and friends from across the quantum community. Plenty of conversations about what’s being built, where the field is heading, and what’s next for quantum in Singapore and beyond... with a few cocktails along the way. Thanks to everyone who came. We’ll have to do it again. #VC #VentureCapital #Deeptech
- What comes after silicon? For decades, advances in materials have shaped advances in technology. Now #quantum technologies are opening up entirely new ways to understand, simulate and ultimately design matter itself. That’s the focus of the third Alain Aspect Symposium, which we are proud to co-organize in Sherbrooke, Québec, from Sept. 28–30. Under the theme Quantum Matter by Design, the symposium will bring together researchers, entrepreneurs and investors across quantum computing, materials science, chemistry, simulation and
- From early conviction to Nasdaq. 🚀 Today, Pasqal begins trading on Nasdaq under the ticker $PSQL. This is a remarkable milestone for the company, and a very special one for Quantonation as we backed Pasqal from the beginning, leading its seed round and its €25 million Series A. At the time, neutral atoms were far from the obvious contender in #QuantumComputing. They were a dark horse. Today, Pasqal is a global quantum computing company entering the public markets with $360 million in gross proceeds to support its next stage of
- For electronics, the transistor changed everything. Could nonlinear photonics be approaching its own transistor moment? For decades, we’ve been extraordinarily good at guiding light. The harder problem has been controlling it. Switching, mixing and converting optical signals efficiently enough to build compact, scalable systems. That’s the problem PINC Technologies Inc. is tackling. The Caltech spinout is building integrated nonlinear #photonic chips and laser engines on thin-film lithium niobate, with the potential to make
