Heisenberg scaling with classical long-range correlations
journal contribution
posted on 2023-06-09, 12:10 authored by Samuel Fernández Lorenzo, Jacob DunninghamJacob Dunningham, Diego PorrasThe Heisenberg scaling is typically associated with nonclassicality and entanglement. In this work, however, we discuss how classical long-range correlations between lattice sites in many-body systems may lead to a 1=N scaling in precision with the number of probes in the context of quantum optical dissipative systems. In particular, we show that networks of coupled single qubit lasers can be mapped onto a classical XY model, and a Heisenberg scaling with the number of sites appears when estimating the amplitude and phase of a weak periodic driving field.
