Investigation of the Manipulation of Quantum Interference Via Dephasing using Akaike Information Criterion
Quantum interference (QI) and Autler-Townes splitting (ATS) are two different effects in atom-field interaction systems.In an electromagnetically induced transparency (EIT) system,when the intensity of the coupling field is moderate,these two effects exist simultaneously.The coupling field Rabi frequency is generally responsible for distinguishing them,and Akaike information criterion (AIC) can be used to quantificationally determine their relative weights.Here,we investigate the manipulation of QI with dephasing in atomic systems based on AIC method.We find that by adjusting the dephasing rates,the transition between QI and ATS,and the transition between destructive and constructive interference can be observed.The precision control of dephasing can be realized by using the phase correlation between the coupling and probe fields,allowing the changing of the weights of QI and ATS,and the greatly enhancement of QI.This enhancement effect has a practical significance on quantum technology.
