Ncomms Non Hermitian

April 6, 2025

2025


We watched a supersonic mode travel across an 18-site fermionic chain on Quantinuum’s H1 — a correlation front that the Lieb–Robinson bound forbids in any Hermitian system. Observation of a non-Hermitian supersonic mode on a trapped-ion quantum computer, in Nature Communications with Juan Carrasquilla and Yong Baek Kim.
