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…

An engaging account of the remarkably rich scientific legacy of physicist Luis Alvarez. nybooks.com/articles/2026/…

From 150K to 200K in less than 6 months. Why?

Siblings: Three of my scientific "children" (Dariel Mok, Hui Khoon Ng, Hoi-Kwong Lo) gather in Singapore. I've been blessed with many wonderful students.

While attending the Q2B Silicon Valley conference in December, I had this enjoyable conversation with Antonella Navarro, host of The Quantum Revolution podcast. youtube.com/watch?v=_ZaspV…

In part 2 or a 3-part series, Dominik Hangleiter continues his thoughtful assessment of the evidence for quantum advantage in random-circuit-sampling experiments. quantumfrontiers.com/2026/01/25/has…

It's fun to describe quantum teleportation in terms of particles that move both forward and backward in time. And it's more than just fun: the intuition derived from that description can guide us to new applications. quantumfrontiers.com/2025/12/14/mak…
