Fantastic. Fwiw, I was taking Feynman's class on computing at the time this was written, and his opinion was similar.
(Also fwiw, it's okay to admire Feynman's scientific accomplishments and general cleverness, but be careful of putting him on too high a pedestal.)

Michael Frank has long worked to make practical reversible computers, which would save considerable energy by not deleting data.

Retweeting this for the folks (myself included) that weren't online over the long weekend

PauliPropagation.jl is open source library that you can use to approximately simulate quantum circuits

We explain the nitty gritty of how these algorithms work in practise in our latest companion paper

If you are interested in quantum computing, I strongly recommend this insightful article by @caltech.edu
student @robbieking1000.bsky.social calling for a "scrappier approach" to finding new applications.

🎉I am very happy to see our Barren Plateau Review published in Nature Review Physics. This article condenses 6 years of our LANL work, but also so many amazing papers by the community!!

"XYZ ruby code: Making a case for a three-colored graphical calculus for quantum error correction in spacetime"

journals.aps.org/prxquantum/a...

This work presents a new highly attractive #Floquetcode in #quantumerrorcorrection and introduces - yet another - useful graphical calculus.

Hey! On the arXiv today we present `Majorana Propagation’ a new classical algorithm for simulating Fermionic circuits.

Depending on your mood... the algorithm can be viewed either as naturally suited to compete with, or collaboratively enhance, quantum hardware simulations.

Two talks with contributions from Coherent Computing at the APS Global Physics Summit this week:

- Techniques for design and training of large quantum machine learning models, presented by me

Water wires are short-lived chains of water molecules linked by hydrogen bonds. Researchers have devised a way to measure them optically. The new technique could be used to study how water-wires influence proton transfer and other biochemical processes.

"I speculated on a new kind of forthcoming NISQ era defined by the birth of a Noisy Individual Semi-topological Qubit. To less blatantly rip off John Preskill’s famous acronym, I also—jokingly of course—proposed the alternative nomenclature POST-Q (Piece Of S*** Topological Qubit)."

Worth a read! 👇

Ever since the Turing test, the idea of having a dialogue with a machine to probe its cognitive abilities (‘thought’) has been inextricably associated with the field of AI.

"How to evaluate the cognitive abilities of LLMs"

In their roadmap, Microsoft described a protocol for demonstrating a topologically protected qubit. There is no publicly available evidence that this test has been conducted successfully. I hope we will hear more soon.

Does P=NP? It’s one of the most fundamental problems in computer science. But, what is P? What is NP? We explain in our complexity class primer: https://buff.ly/2zQbD7I

I read this when it first came out, when I was taking grad classes and doing research. It's still just as important now as it was then, and a paper I think about a lot.

Myths around quantum computation before full fault tolerance: What no-go theorems rule out and what they don't
