⚛ 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…

As timelines tighten, details might benefit attackers more than defenders. So we're trying something weird: proving a circuit exists without revealing it. For example, here's a zero-knowledge proof that we found 10x smaller quantum circuits for ECDLP: github.com/tanujkhattar/z…

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…

Today we are announcing Oratomic. Based in Pasadena, our goal is to build the world’s first fault-tolerant quantum computer using neutral atom qubits. Last Fall, I came to fully appreciate the potential of neutral atoms combined with high-rate error correction. Soon after, I made the decision to leave Google and Berkeley to go all-in on what is now Oratomic. My teammates are truly exceptional, and it’s an honor to work alongside them with a chance to make history. If you are excited by this mission, please get in touch! Website → oratomic.com

Dominik Hangleiter weighs in with an informative post about a much debated question: Has quantum advantage been achieved? This is the first post in a three-part series. quantumfrontiers.com/2026/01/06/has…

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/qua…

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

One of my first encounters with closed timelike curves (CTCs) took place when I read The Eyre Affair as a teen. I didn't expect to become a physicist who co-writes papers about simulating CTCs to improve quantum metrology. quantumfrontiers.com/2025/12/14/mak…

Today marks (at least roughly) the 404th Thanksgiving...and my 150th post for Quantum Frontiers! Only 254 to go to catch up, right? quantumfrontiers.com/2025/11/26/wha…

The world needs more of the creativity, humor, and warmth of Diana Wynne Jones’s novels. @Balticon quantumfrontiers.com/2025/09/21/ble…

6,100 neutral-atom qubits trapped in a grid by lasers @Caltech ... is a lot. caltech.edu/about/news/cal…

Happy to see that our work with @RobertHuangHY and @preskill is now published! We use shadow overlap to make machine learning of quantum systems verifiable, and to benchmark & optimize quantum circuits.

I’m deeply honored to receive the 2025 Academic Pioneer of the Year Award from the Quantum World Congress. Curiosity-driven fundamental research revealed the promise of quantum science and technology, and will be just as vital for future advances. quantumfrontiers.com/2025/09/18/joh…

For science.

There is no solo leveling in science, or in gaming. The adventure is best experienced together. Thanks for having us, @BASILISK_gg.
