Computing with many encoded logical qubits beyond break-even High-rate quantum error correcting (QEC) codes encode many logical qubits in a given number of physical qubits, making them promising candidates for quantum computation. Implementing high-rate codes a...

Same here, only realised because they emailed me. The fact it had to be a manual update is pretty bad (... makes you feel a little better about your own release oopsies though)

Much of our work with the Guppy language has been about programming and executing adaptive programs, to encourage exploring these ideas. We're finding though that makes the kind of things Stim is uniquely good at hard to replicate. It's an interesting tension point to explore.

Must say I'm having a great time running arch off an external SSD. Windows is still sitting inside the case in case of emergency but I haven't had to resort to it yet.

KDE is really good now!

Helios: A 98-qubit trapped-ion quantum computer 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...

Quantum Error-Corrected Computation of Molecular Energies We present the first demonstration of an end-to-end pipeline with quantum error correction (QEC) for a quantum computation of the electronic structure of molecular systems. Using Quantinuum H2-2, we c...

What's this? Some very nice work by my colleagues.

Still reasonably unstable but hopefully minimally usable now!

Digital quantum magnetism at the frontier of classical simulations The utility of near-term quantum computers for simulating realistic quantum systems hinges on the stability of digital quantum matter--realized when discrete quantum gates approximate continuous time ...

Hi #quantum bluesky 👋 In arxiv.org/abs/2503.20870 with #Quantinuum, Fermioniq, Caltech, EPFL, TUM we show Quantinuum's H2 ion-trap #quantumcomputer can simulate dynamical evolution of a 2D Ising model at late times and sizes pushing beyond classical means(MPS, PEPS, sparse Pauli propagation, NN).

Hamiltonian dynamics simulation using linear combination of unitaries on an ion trap quantum computer The linear combination of unitaries (LCU) method has proven to scale better than existing product formulas in simulating long time Hamiltonian dynamics. However, given the number of multi-control gate...

New paper dance! This is mainly the work of Michelle Sze in our chemistry team, but I want to also big up the TKET team (Silas and Yao) for making the compiler absolutely rip on those LCU circuits.
