Comprehensive tutorial connecting classical and quantum synchronization phenomena. Covers limit cycles, phase locking, Kuramoto models, and quantum limit cycles with analytical tools for analyzing synchronized states in quantum systems.
Kerr nonlinearity enables precise control of quantum synchronization through amplitude-dependent frequency shifts, revealing a simple linear scaling between Kerr strength and required squeezing for phase locking in driven quantum oscillators.
