Even on the bad days, there are good things to celebrate and enjoy. quantumfrontiers.com/2026/05/20/nic…
I'm quite amazed, and deeply honored, to see my name on this distinguished list of "AI Pioneers." Thank you, @BostonGF and AI World Society, for recognizing that quantum science can contribute to "an age of human flourishing." bostonglobalforum.org/publication/16…
From dream to reality: The bridge connecting quantum information and matter to high energy physics @Caltech now exists.
Everybody loves entropy, yet somehow we are always working hard to reduce it. quantumfrontiers.com/2026/04/12/how…
Wise words from Garnet Chan on quantum computing and chemistry. newquantumera.com/podcast/quantu…
Our paper “Exponential Quantum Advantage in Processing Massive Classical Data” proves that quantum machines can solve common machine learning tasks using exponentially less memory than a classical machine would require. Much further work will be needed to translate this theory into practice. But because modern AI is often hampered by insufficient memory, this finding bolsters our confidence that quantum AI can eventually have a broad impact on daily life. This project was led by the remarkable Caltech student @haimengzhao and inspired by the vision of @RobertHuangHY, with essential contributions from all our collaborators. Here Haimeng tells the story. quantumfrontiers.com/2026/04/09/unl…
⚛ Can small quantum computers accelerate AI on massive classical data? Yes! I am absolutely thrilled to share our new work proving *honest* exponential quantum advantages in broadly applicable classical tasks. 🧵👇 Paper: arxiv.org/abs/2604.07639 Blog: quantumfrontiers.com/2026/04/09/unl…
The Caltech group knows it has years of work ahead before any of its dreams have a chance of coming true. But the researchers can’t wait to get started. “Pick a cooler life quest than building the world’s first quantum computer with your friends!” said a jubilant @DolevBluvstein [CEO of @TeamOratomic ], reached by phone shortly before their paper went live, before rushing off to celebrate. quantamagazine.org/new-advances-b…
With extraordinary colleagues, we are developing new architectures for neutral-atom quantum processors that dramatically reduce the resource estimates for fault-tolerant quantum computing. This progress makes me optimistic that broadly useful quantum computing will soon be a reality. We’ll continue fundamental research @Caltech to advance quantum science and technology, while building fault-tolerant quantum machines and exploring their applications @TeamOratomic. It’s a very exciting time to be a quantum scientist! caltech.edu/about/news/cal…
@jenseisert Yes, except for omitting “fraught”!
I'm looking forward to the Kavli Symposium tomorrow at the APS Global Physics Summit, where I'll speak about "The Road to Quantum Advantage" summit.aps.org/events/MAR-X02
I'm thrilled that Charlie Bennett and Gilles Brassard have received the A. M. Turing Award for “their essential role in establishing the foundations of quantum information science and transforming secure communication and computing.” Congratulations! quantamagazine.org/quantum-crypto…
In this thoughtful essay, Garnet Chan reflects on recent progress using classical heuristics in computational quantum chemistry—and what it means for quantum computing. The lessons he draws can help to steer both classical and quantum approaches in scientifically productive directions. quantumfrontiers.com/2026/03/12/the…
Today was the last meeting of our first-year seminar @Caltech: "Quantum information science today and tomorrow." I'm grateful to (from left to right) Andy, Jin, Fan, Ostap, Justin, Idil, Lily, Ella, and Ronald for their sparkling enthusiasm and many perceptive insights.
With characteristic attention to detail, @nicoleyh11 offers guidance on handling faculty offers. quantumfrontiers.com/2026/03/11/nic…
In the last post of a 3-part series, Dominik Hangleiter highlights the importance of efficient verification of quantum advantage, and assesses the prospects for achieving it soon. quantumfrontiers.com/2026/02/28/wha…
It's nice to find out that I'm still an influencer in particle theory: "We thank John Preskill for suggesting the phrase “One Sum To Rule Them All,” which inspired the title of this paper." arxiv.org/abs/2602.22320
Interesting format for a review article. 24 brief chapters, each offering perspective from a small subset of the 69 authors on a particular topic. quantumfrontiers.com/2026/02/11/qua…
