Lieb–Robinson bounds are a set of results in mathematical physics that describe the ability of a disturbance in a quantum many-body system to propagate through the system over time. Named after physicists Elliott Lieb and Derek Robinson, these bounds provide a way to quantify how quickly information or correlations can spread in a quantum system, especially in the context of local Hamiltonians. \#\#\# Key Concepts 1.
