Abstract:We provision a viewpoint into measuring the quantum data spreading by introducing N-operator correlators. Leveraging the idea from N-point association function from cosmology, we formulate a generalized Out-of-Time-Ordered Correlator (OTOC), called N-Operator Correlator (NOC). Such formulation can decrease the consequence of restricted inspection connected alongside selecting lone two operators for OTOC. NOC can obtain into document a larger set of measure probes in measuring the flat of quantum data spreading. We display these concepts alongside two analytically tractable toy systems alongside computing thermal averages of controller period evolutions at a finite temperature: a sole qubit in longitudinal site and XYZ two-qubit system. Our viewpoint serves as a essential introduction to generalized controller correlators in quantum mechanics.
