Scientist working in the field of computational quantum chemistry and physics. More recently, I’ve started exploring quantum computation for electronic structure calculations.
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.

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...

👻 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.
