This theoretical proposal outlines a method for measuring correlation functions in quantum field systems by utilizing local and nonlocal quantum quenches as perturbations. The approach demonstrates how short-term disturbances can reveal initial state correlations, offering a pathway to study non-Gaussian correlations in massive and massless scalar field theories. While highly relevant to fundamental quantum physics, this work addresses the core mechanics of quantum systems rather than applied AI or quantum computing architectures.
Measuring correlations using local and nonlocal quenches
arXiv:2609.24873v1 Announce Type: cross Abstract: We present a theoretical proposal for measuring correlation functions in a quantum field system based on the use of quantum quenches. Using the examples of massive and massless scalar field theories, we show that a short-term perturbation of the system leads to a dependence of the further evolution of the average field on the initial state's correlation functions. Considering two types of perturbations, namely local and nonlocal quenches, we show which correlation functions can be measured in each of these cases. The proposed procedure can be applied to study non-Gaussian correlations.
