Super nice result from my colleagues @marklt.bsky.social @riverlane.com showing the NP-hard-ness of min-weight colour code decoding! scirate.com/arxiv/2603.0... 🧠

Minimum Weight Decoding in the Colour Code is NP-hard

All utility-scale quantum computers will require some form of Quantum Error Correction in which logical qubits are encoded in a larger number of physical qubits. One promising encoding is known as the...

👻 We ain’t afraid of no ghost! A new #arXiv paper from our team proposes the 'ghost protocol’ to enable AMO qubits to catch up with superconducting qubits, which lag in #QEC cycle speeds. It addresses the challenges of scalable #QuantumErrorCorrection in the context of fast transversal logic👇🧪

In a new paper today with @aleksei-quantum.bsky.social and @abaysmidt.bsky.social, we demonstrate a practical numerical approach to provide tight bounds on Trotter error. scirate.com/arxiv/2510.1...

A Monte Carlo approach to bound Trotter error

Trotter product formulas are a natural and powerful approach to perform quantum simulation. However, the error analysis of product formulas is challenging, and their cost is often overestimated. It is...
