🥳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
Check out new work, led by @nickblunt.bsky.social, on efficient estimation of Trotter Error
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.

👻 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👇🧪
We have an open rolling advert for QEC researchers at Riverlane. And now also have a single post to fill for an (error-corrected) algorithms researcher

the accuracy problem you described can be attributed to any known classical algorithm because of its heuristic nature. We cannot say in advance what error is before we run calculations. This is why I find some quantum algorithms such as QPE fascinating, we can put the error bar in advance.
An initio method is one which depends on the fundamental constants only such as charge of an electron, etc. The more non-fundamental constants (parameters) one introduces in a model the less it becomes ab initio and more empirical. This is why PBE is more empirical than any CC method.
#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.
