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/m...

Every December since 2017, I've delivered a keynote at Q2B Silicon Valley, commenting on recent progress in quantum computing. Here is what I said this time. It's been a good year for quantum. quantumfrontiers.com/2025/12/26/q...

In predicting properties of electronic structure or deciphering signals produced by Nature, will classical artificial intelligence eat quantum's lunch? Here @robbieking1000.bsky.social considers the issue from the perspective of complexity theory. quantumfrontiers.com/2025/12/11/c...

The Institute for Quantum Information (and Matter) @caltech.edu is celebrating its 25th anniversary. It has been a great run so far, and quantum information science is more fun now than ever! www.caltech.edu/about/news/c...

"... physicists adore apparent contradictions ..." Yes we do! Doesn't everyone? quantumfrontiers.com/2025/10/26/t...

The annual retreat of @caltech.edu's Institute for Quantum Information and Matter (IQIM) is an opportunity to spend the weekend with some of my favorite scientists. It is always an uplifting and illuminating experience.

Now under construction: The bridge connecting research on quantum matter and quantum information in the Ginsburg Center @caltech.edu to the high energy theory group in Downs-Lauritsen Laboratory. Exciting!

When and how will quantum computing broadly benefit humanity? Despite exhilarating recent progress, we still don’t know. Here my friend Jens Eisert and I assess the current status and the challenges ahead. arxiv.org/abs/2510.19928

Aside from Yang-Mills theory and parity nonconservation, Yang made so many profound contributions to physics! One that deeply impressed me as I was starting grad school: a 1975 paper with T. T. Wu highlighting the role of fiber bundles in gauge theory. www.nytimes.com/2025/10/18/s...

Thanks, Ingrid Fadelli, for this nice article about our recently published paper with Robert Huang and Mehdi Soleimanifar. The paper describes a surprisingly simple protocol for verifying that a many-qubit state in the lab matches a desired target state. phys.org/news/2025-10...
