We are excited to share that members of The Matter Lab presented their latest research at the Canada–Korea Conference on Science, Technology and Innovation (CKC 2026), held on June 21–25 ⚛️ [1/6]

Andy Extance explores how scientists across disciplines can benefit from careful use of artificial intelligence tools, from small groups to those at tech giants like Meta, Google and Nvidia. www.chemistryworld.com/features/ai-...

‘In any catalysis problem, there are lots of variables, and it’s a case of seeing how you’re varying them,’ says Graham Hutchings from the University of Cardiff. @andyextance.bsky.social www.chemistryworld.com/features/ai-...

A new member of the El Agente family - “El Agente Seguro: An Agent for Chemical Safety” is now on ChemRxiv 🤖 🔗 chemrxiv.org/doi/full/10.... It focuses on one of the most important challenges for AI-driven chemistry and self-driving laboratories: safety. [1/7]

Curious to see what’s going on at the Matter Lab? Join us at CSC Toronto as our group members present their latest research in computational chemistry, machine learning, and materials science. We’d love to connect and share our work with you!

From alchemy to AI-chemy: how will AI reshape the future of chemistry and materials discovery? In Dædalus, @aspuru.bsky.social reflects on the relationship between matter, minds, and tools, from the rise of modern chemistry to today’s AI-driven systems. 🔗 www.amacad.org/publication/... [1/4]

🚀Excited to share our latest work: “Optimizing ground state preparation protocols with autoresearch”. We explore how language-model coding agents can automate the optimization of ground-state preparation protocols in quantum computing & classical quantum simulation. 🔗 arxiv.org/abs/2604.25610 [1/4]

The broader idea: if a quantum routine can be executed and scored, coding agents can help automate part of the tedious hyperparameter/protocol-search loop. Kudos to @realmantilla.bsky.social, Jérôme F. Gonthier, Ignacio Gustin, @variniabernales.bsky.social, and @aspuru.bsky.social 🎉 [4/4]
