@JakeArkinstall: The Helios paper from @QuantinuumQC is out on arxiv - It is feat of quantum hardware and software. If you follow me, you're probably a software nerd. I want take a scenic tour of a......

The Fermi-Hubbard model is the starting point for the simulation of many strongly correlated materials, including high-temperature superconductors, whose modelling is a key motivation for the construc...

We report on Quantinuum Helios, a 98-qubit trapped-ion quantum processor based on the quantum charge-coupled device (QCCD) architecture. Helios features $^{137}$Ba$^{+}$ hyperfine qubits, all-to-all c...

We introduce the Hierarchical Unified Graph Representation (HUGR): a novel graph based intermediate representation for mixed quantum-classical programs. HUGR's design features high expressivity and ex...

Quantinuum are hiring a research software engineer to work on compilation of fault-tolerant quantum software for the next generation of quantum computers. Quantum software relies on quantum error corr...

The 2025 Alonzo Church Award for Outstanding Contributions to Logic and Computation is presented to **Paul Blain Levy** for his fundamental study of effectful λ-calculi through the Call-by-Push-Value calculus. The awardee book and paper are: > Paul Blain Levy. Call-By-Push-Value: A Functional/Imperative Synthesis. Semantics Structures in Computation 2, Springer 2004, ISBN 1-4020-1730-8 > > Paul Blain Levy. Call-by-Push-Value: Decomposing call-by-value and call-by-name. High.-Order Symb. Comput. 19(4): 377-414 (2006) ## The Contribution Initiated by Alonzo Church, the research programme into the λ-calculus as an abstract model of computation has spurred volumes of fundamental research in logic and computation. By the end of the 20th century, the studies of the λ-calculus in its purely logical form and its applied effectful form bifurcated. In an outstanding contribution, Levy has reunited the many existing research streams into the study of one subsuming calculus: Call-by-Push-Value (CBPV). Levy developed and presented an extraordinarily large body of evidence spanning a cross-section of the semantic theory of the λ-calculus and its application to programming language modelling, including: algebraic datatypes, operational semantics, denotational semantics, and equational theories. To date, CBPV remains a unifying starting point in the study of computational and logical phenomena, including: effects, polarisation, term normalisation, type-isomorphisms, and program transformations. In addition to its scientific contribution, the nominated monograph is a unique access-point into the culmination of decades of logic and programming language semantics.
