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:

Quantum circuits are just a phase
Quantum programs today are written at a low level of abstraction - quantum circuits akin to assembly languages - and even advanced quantum programming languages essentially function as circuit descrip...

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!)

Why Bell Labs worked so well, and could innovate so much, while today’s innovation, in spite of the huge private funding, goes in hype-and-fizzle cycles that leave relatively little behind, is a qu...

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:

Hadamard-$Î $: Equational Quantum Programming
Quantum computing offers advantages over classical computation, yet the precise features that set the two apart remain unclear. In the standard quantum circuit model, adding a 1-qubit basis-changing g...

M*-categories: Where limits in analysis and category theory meet
This article introduces M*-categories: an abstraction of categories with similar algebraic and analytic properties to the categories of real, complex, and quaternionic Hilbert spaces and bounded linea...
