My latest work with jarthurgross and T.J. Volkoff on Quantum error correction-inspired multiparameter quantum metrology has appeared on arXiv arxiv.org/abs/2409.16515

This is a big deal for the costs of quantum algorithms. By many measures space and time costs just went way down, and many optimizations to minimize T counts at the price of more Clifford’s or depth may just have become irrelevant (or will be soon).

Congratulations to Matt Chow who defended his PhD Dissertation yesterday, "Scalable methods for performant control of hyperfine qubits in atoms and ions" supervised Sandia National Labs with Drs. Susan Clark and Yuan-Yu Jau. Great job Matt!

Can we convert atom loss to an erasure error for neutral atoms? In my latest work with Vikas Buchemmavari, Michael J. Martin, and Ivan Deutsch on arXiv arxiv.org/abs/2410.23430, we give a framework to do it.

wow, incredible progress on fault-tolerant quantum computing with qLDPC codes, achieving constant space overhead and polylog-time overhead arxiv.org/abs/2411.03683 arxiv.org/abs/2411.03632

NPJ call for paper for a collection of QEC articles with great editors. Submit before July 23rd 2025: shorturl.at/XNQIQ

Atom loss is detected during computation without disturbing the quantum state, an important task for long computations with neutral atoms. Sandia National Labs 🔗 go.aps.org/3Dd82lm

Our paper is published in PRX Quantum today! We explore how to deal with leakage errors and atom loss in Neutral atom systems. Great Collaboration with folks at Sandia, and UNM colleagues Sivaprasad Omanakuttan and Ivan Deutsch

Supremacy Debates: A Transcript. Recently, I witnessed a moderated debate between a classical computer and a quantum computer to determine who really is better. Here are my notes transcribed for my friends. pradeepniroula.com/notes/supremac…

Submissions for QEC 2025 are now open through March 28. This will easily be the most exciting conference on quantum error correction yet! Conference homepage: qec25.yalepages.org EasyChair submission page: easychair.org/my/conference?…

I was thrilled to learn of Quantinuum’s expansion into New Mexico. This is a huge advance in our state's quantum technology development. We're super excited for the partnership with the Quantum New Mexico Institute Univ. of New Mexico. New Mexico is a Quantum State!

I have been encouraged to publish my talk at Q2B 2024. It's arXiv.org today. arxiv.org/abs/2502.17368

Almost exactly a year ago, we ran an ambitious experiment. The goal was to make a quantum computer do something that was impossible before and would also be practically useful. Today, I am proud to announce the results of that work through a paper in Nature. In it, we use a

Wojciech Zurek is the father of our modern understanding of decoherence, and in my opinion has delivered more insight on the foundation of quantum mechanics than any living person. He's finally written the definitive book on his approach!
