One of the most-cited arguments for near-term quantum advantage in chemistry just got a rigorous classical answer — from one of the world's leading quantum chemists. Garnet Chan's group at Caltech sol...

Charles Bennett and Gilles Brassard were recognized for their foundational work in quantum information science.

Recently, my coworkers and I put out a preprint “Classical solution of the FeMo-cofactor model to chemical accuracy and its implications’’ (Zhai et al. 2026). It is a bit unusual to write comm…

It’s happening.  Your inbox registers an email from the chair of a faculty-hiring committee. With trembling fingers, you click on the message. “We were very impressed…we’re delighted to offer……

We are now at an exciting point in our process of developing quantum computers and understanding their computational power: It has been demonstrated that quantum computers can outperform classical …

We show that within the Standard Model any system of hadronic weak charm decays related by $U$-spin satisfies the following rate sum rule: (sum of CF and DCS CKM-free rates) divided by (sum of SCS CKM...

My husband and I visited the Library of Congress on the final day of winter break this year. In a corner, we found a facsimile of a hand-drawn map: the world as viewed by sixteenth-century European…

Luis Alvarez brought a scientific pragmatism to many of the twentieth century’s greatest mysteries, including the secrets of pyramids, the Kennedy assassination, and the disappearance of the dinosaurs...

During the spring of 2022, I felt as though I kept dashing backward and forward in time.  At the beginning of the season, hay fever plagued me in Maryland. Then, I left to present talks in sou…

On December 10, I gave a keynote address at the Q2B 2025 Conference in Silicon Valley. This is a transcript of my remarks. The slides I presented are here. The first century We are nearing the end …

AI promises to revolutionize the way we do science, which raises a central technological question of our time: Can classical AI understand all natural phenomena, or are some fundamentally beyond it…

John Preskill reflects on the history and impact of IQIM

The U.S. Department of Energy today announced $625 million in funding to renew its five National Quantum Information Science Research Centers.

This October, fantasy readers are devouring a sequel: the final installment in Philip Pullman’s trilogy The Book of Dust. The series follows student Lyra Silvertongue as she journeys from Oxford to…

Quantum computing is advancing rapidly, yet substantial gaps separate today's noisy intermediate-scale quantum (NISQ) devices from tomorrow's fault-tolerant application-scale (FASQ) machines. We ident...

Quantum information systems, systems that process, store or transmit information leveraging quantum mechanical effects, could, in principle, outperform classical systems in some optimization, computat...

The Nobel Prize in Physics 2025 was awarded jointly to John Clarke, Michel H. Devoret and John M. Martinis "for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an...

The neutral-atom platform shows promise for scaling up quantum computers.

The 2025 Quantum Leadership Awards were announced at the Quantum World Congress on 18 September 2025. Upon receiving the Academic Pioneer of the Year Award, John Preskill made these remarks. I’m en…
