|Abstract:||We exploit the relationship between classical instability and entanglement to control the creation of entangled states in an open system of three coupled quantum parametric oscillators at high temperature. Introducing a suitable pulsed perturbation in the classical system we are able to control the transition from stable to unstable behaviour. Entanglement arises in the same parameter regions where the classical system is unstable displaying features different from the case of two coupled oscillators. Entangled states are particularly sensitive to negative pulses and to the size of the duty cycle.|
