Congratulations Anna Maria Rey Ayala of CU Boulder 🦬, National Institute of Standards and Technology, and JILA, newly inducted #NASmember! #NAS161 #physics

Ah yes, losing a full day's work to a sign error. I feel like a physicist again.

I have heard folklore that error correction is impossible in classical analog systems, but I can't seem to find a good reference for this claim. Does anybody have any good leads? Is it even correct?

Spin-cat codes in neutral-atom qudits yield the potential for fault tolerance with a high threshold and low resource overhead. Sivaprasad Omanakuttan Ivan Deutsch Vikas Buchemmavari jarthurgross #CQuIC Univ. of New Mexico go.aps.org/3RgbG29

Very excited to see this in press. Led by Sivaprasad Omanakuttan & Milad Marvian, with Vikas Buchemmavari and jarthurgross, we show how large spin systems can be used to reach high-threshold/low-resource fault-tolerant quantum error correction. Atomic spins are the natural platform.

I'm thrilled to join Global Technology Applied Research at JPMorgan Chase today to focus full-time on quantum error correction, from fault-tolerance experiments to new code development. Looking forward to working with Marco Pistoia, Ruslan Shaydulin, Sivaprasad Omanakuttan, and others!

Today we introduce the BP+OTF decoder (scirate.com/arxiv/2409.014…), an almost-linear time decoder for quantum LDPC codes. Importantly, we aim to do so for circuit-level noise. 🧵

New paper out today with colleagues from Donostia-San Sebastian. A linear-time decoder for QLDPC codes and a new method for sparsifying detector error models.

Been working on "Magic state cultivation: growing T states as cheap as CNOT gates" all year. It's finally out: arxiv.org/abs/2409.17595 The reign of the T gate is coming to an end. It's now nearly the cost of a lattice surgery CNOT gate, and I bet there's more improvements yet.

Even if you don't care one bit about scientific research, it's important to recognise the value of publicly funding people working on very hard problems and training bright young minds on how to solve them. Do you think it’s a coincidence that so many successful entrepreneurs

Anybody familiar with linear algebra over rings? I want to find the null space of a matrix whose entries are elements of a (finite) group algebra (over a finite field). Help?
