We survey the inclusion of interferometric elements in nonlinear spectroscopyperformed with quantum light. Controlled interference of electromagnetic fieldscoupled to matter can induce constructive or destructive contributions ofmicroscopic coupling sequences (histories) of matter. Since quantum fields donot commute, quantum light signals are sensitive to the order of light-mattercoupling sequence. Matter correlation functions are thus imprinted by differentfield factors, which depend on that order. We identify the associated quantuminformation obtained by controlling the weights of different contributingpathways, and offer several experimental schemes for recovering it. Nonlinearquantum response functions include out-of-time-ordering matter correlators(OTOC) which reveal how perturbations spread throughout a quantum system(information scrambling). Their effect becomes most notable when usingultrafast pulse sequences with respect to the path difference induced by theinterferometer. OTOC appear in quantum-informatics studies in other fields,including black holes, high energy, and condensed matter physics.
