- Abstract
We investigate the phenomenon of quantum transient synchronization in an open quantum system comprising a qubit interacting with a non-Gaussian fluctuating colored-noise environment. The spectrum of this environment follows a power-law form of 1 / f α . We employ the Husimi Q-function and the synchronization measure S-function to measure the occurrence and strength of phase locking. The findings reveal that Markovian and non-Markovian dynamics contribute to quantum synchronization, with their significance dependent on the parameter α . Our analysis hints at a transition between Markovian and non-Markovian behavior in the pure dephasing evolution, estimated around α ≈ 1 . Furthermore, the Arnold tongue phenomenon offers additional evidence to support our observations. Deviating from the α ≈ 1 value increases the likelihood of synchronization while increasing the number of fluctuators narrows down the synchronization region.
