Quantum computing is usually framed in complex linear algebra. This paper asks: what is the least you need to add to reversible classical computing to recover quantum computation? www.pnas.org/doi/10.1073/... @manchegobaby.bsky.social

At the closing of the UN International Year of Quantum today, the Quantum Software Alliance was born! Founded by institutions from 15 countries over 4 continents, QSA will champion and co-ordinate the development of #quantumsoftware: quantumsoftwarealliance.org

The number of low-quality or fraudulent publications is rising to hundreds of thousands per year. It is time to reevaluate current publishing models and outline a global plan.

Coverages, or Grothendieck topologies, describe when a collection of regions covers another region in a space. But what if your space is a spacetime? The topological space may have a causal order saying which (spacetime) points 'come before' which other points, for example.

Have you ever wondered why we describe circuits with matrices? I mean, circuits are about tensor products, while matrices are about direct sums. This new paper with Louis Lemonnier and @manchegobaby.bsky.social gives a practically useful explanation: arxiv.org/abs/2510.05032.

A new quantum programming construct: more abstract than circuits, capturing important examples elegantly and in fact universal, yet simple and intuitive. With prototype compiler and clean categorical semantics to boot! With Alex Rice, Chris McNally, and Louis Lemonnier: arxiv.org/abs/2507.11676

I presented a taster poster on our upcoming work in distributed quantum compilation at the Uni of Edinburgh’s Informatics internal research showcase this Tuesday. Focus: our upcoming model/hardware-agnostic intermediate representation for compilation of quantum programs (quite a mouthful I know!)

A discussion of the success of Bell Labs as a research organization and why we have nothing like it anymore.

A sound and complete finite system of equations to manipulate Toffoli+Hadamard quantum circuits you say, so you can automate circuit optimisation, you say? Why of course, here you go: arxiv.org/abs/2506.06835, with Wang Fang and @manchegobaby.bsky.social.

90% of doing science is being open to new ideas.

🚨 New preprint alert 🚨 Always wanted to know the connection between analytic limits and categorical limits? Tired of having to establish directed colimits of contractions when directed colimits of isometries suffice? You're in luck! Now on www.arxiv.org/abs/2505.17432. With Matt Di Meglio.
