A three-qubit kicked-top model — a toy quantum system kicked repeatedly — can be tuned between order and chaos: symmetric vs. asymmetric qubit interactions drive the system from periodic, entanglement-free revivals to quasi-periodic dynamics where entanglement persists, demonstrating the quantum-classical correspondence between regular motion and chaos in a system small enough to fully analyze.
