How Time Works in Quantum Systems: Overview of time ordering and time correlation in weakly perturbed atomic collisions and in strongly perturbed qubits

J. H. McGuire, L. Kaplan, Kh. Kh. Shakov +5

Time ordering may be defined by first defining the limit of no time ordering (NTO) in terms of a time average of an external interaction, V(t). Previously, time correlation was def…
