"We're all worried," as what it means to do research (in my field, Theoretical CS) seems to be shifting, and shifting fast. What to do? Senior researchers must lead by example, knowing that not everything will pan out. What I'm suggesting below may not work everywhere, but here's my own advice: 1/

🥳Excited to share our new paper: "Minimum Weight Decoding in the Colour Code is NP‑hard" We prove there's no algorithm to find the best way to correct errors in reasonable time for the colour code So, let’s focus on heuristic/approx algorithms: scirate.com/arxiv/2603.0... @marklt.bsky.social

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...

Quantum Computation of Electronic Structure with Projector Augmented-Wave Method and Plane Wave Basis Set
Quantum simulation of materials is a promising application area of quantum computers. To practically realize this promise, we must reduce quantum resources while maintaining accuracy. In electronic st...

👻 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👇🧪

#compchem and #drugdiscovery people - do you have any good references for where quantum chemistry actually makes a big difference or could make a big difference in the drug discovery process? To my understanding - often, the sampling error is much bigger than the electronic error when using FFs.
