After the smash hit debut album "NISQ", @preskill.bsky.social releases his long-awaited sophomore project "Megaquop". Critics laud the forward thinking and maturity evident in this release but wonder -- can lightning be caught in a bottle twice? arxiv.org/abs/2502.17368

@quantiki.bsky.social Is the website down? I keep getting this message on Firefox.

ArXiv quant-ph needs to be split up! Paul Ginsparg lists Daniel Gottesman's proposed subcategories at his @aspenphysics.bsky.social talk. He is looking for feedback: please reply, dm, or email.

Recently, I was rereading Carl Sagan’s book, "The Demon-Haunted World: Science as a Candle in the Dark" published in 1995. I am just now randomly posting a paragraph from it; you know, any resemblance to actual events is purely coincidental.

Curious about when Pauli twirling can be used to improve the performance of a quantum error mitigation technique like Zero-noise extrapolation (ZNE) ? I added a tutorial in #mitiq exploring this.

Emmy Noether showed that fundamental physical laws are really just a consequence of simple symmetries. A century later, her insights continue to shape physics. @shalmawegs.bsky.social reports: www.quantamagazine.org/how-noethers...

We had fun arguing 🤺 about the prospects of near-term quantum computing in Lapland/Oxford In arxiv.org/abs/2501.05694 we frame our (reasonably converged) conclusions around common 'myths' concerning error mitigation, VQAs, resource estimates and potential applications Feedback/discussion welcomed!

Major update: The zoo is not just a repository, but also a taxonomy. Now, every code page has a visualization of the code's primary ancestors. 🧵

I enjoyed this intuition for the Collatz conjecture. It’s such a fun problem:

Layerwise Richardson extrapolation (LRE) is a quantum error mitigation (QEM) technique defined in (the recently published): journals.aps.org/pra/abstract... LRE has been implemented in mitiq as a QEM method you can use today! mitiq.readthedocs.io/en/stable/gu...

The Putnam math competition happened this past weekend! Made a video of how to work through question A1, which (not surprisingly) was the most "rote" of the bunch. I thought questions A6 and B1 were really neat too. #ITeachMath www.youtube.com/watch?v=ccu-...

Entropy is one of those formulas that many of us learn, swallow whole, and even use regularly without really understanding. (E.g., where does that “log” come from? Are there other possible formulas?) Yet there's an intuitive & almost inevitable way to arrive at this expression.
