Dynamic chaos in the kicked “photon-qubit atom”

Abstract

We study dynamics of a qubit coupled to a single photon mode in a high-quality resonator. For a weak coupling constant the qubit and photon form a long-lived bound state which may be called as a "photon-qubit atom". We consider the stability and chaotic dynamics of the photon-qubit atom under the action of short electromagnetic pulses. The photon oscillator considered in the classical approximation. We plot the Poincare surface to indicate the appearance of the chaotic behaviour. It is shown that depending on the qubit and field parameters the system may be demonstrating the chaotic behaviour.
