An exciting result has just appeared on arXiv, concerning the following simple-seeming problem: if A is a set of n positive integers, then how large a sum-free subset B must it contain? That means that if x, y and z belong to B, then x + y should not equal z. 🧵

There is something at once funny and humbling about this MathOverflow thread in which a bunch of research mathematicians realize they don't know how to answer the question “when does a box of size a×b×c fit inside one of side x×y×z?”. mathoverflow.net/q/282158/17064

I love this kind of questions! With open games, the game tree Hamkins talks about in his answer below is replaced with a more intuitive, dynamical description (this helps greatly when modeling edge cases like castling) 1/n

What is a chess piece, mathematically? I posted an answer to this question some years back on MathOverflow at mathoverflow.net/a/287927/1946.

What an electrifying story about an important new math proof connecting combinatorics, number theory and algebraic geometry, with potential applications in harmonic analysis, reported by @EricaKlarreich in @QuantaMagazine today: quantamagazine.org/merging-fields…

1/n: There are some academic papers that are so brilliantly and so accessibly written and so universal in scope that they transcend disciplines and stand as timeless testaments to both great thinking and great writing. Here's a short personal selection:

TL;DR Here is a video of cat states dancing to his piano music. It shows the evolution of a Fock state towards a large-amplitude squeezed cat state, showing the Wigner function and the phase probability distribution.

Very fortunate to have had the chance to learn about CV state generation from the ever kind and humble Matt Winnel. Excited to get feedback on our new work: "Deterministic preparation of optical squeezed cat and Gottesman-Kitaev-Preskill states". arxiv.org/pdf/2311.10510…

@nicolexandre @jfitzsimons Haha, thanks a lot for the shout-out @nicolexandre! My PhD is focused on implementing and utilising near-term quantum optical architectures, and we recently demonstrated a use case for boson sampling to replace classical hash functions in blockchains: arxiv.org/abs/2305.19865

The physicists Leonard Susskind and Adam Brown have proposed the second law of quantum complexity, a rule similar to the second law of thermodynamics that describes the evolution of complexity in quantum systems. quantamagazine.org/in-new-paradox…

If you have heard buzzwords like quantum, blockchain, energy consumption, climate change, and all that - you might not be the only one. Here we try to present an honest inter-disciplinary analysis of a realisable technology influencing them all.

In the City of Joy, where destinies entwined, a cinematic masterpiece emerged. Martin Scorsese, captivated at age nine, ranks it among the two best color films ever. Shot entirely in India, this behind-the-lens tale unveils a bond of friendship and a cinematic odyssey. 1/17

A new paper introduces a novel way to reduce errors in the preparation of |0⟩ qubit states, not using a conventional method with post-selection (example left) but using a family of CNOT and Toffoli circuits (simplest example right): riverlane.com/blog/a-new-way… #quantumcomputing

I'm very excited to share recent results on preparing topological states by measurement. In our latest collaboration with Quantinuum, we unambiguously provide the first realization of non-Abelian topological order in their latest H2 quantum processor (which launches today!)
