Transitions from Rabi to Josephson dynamics are identified depending on both the intra-qubit interactions to field-ensemble coupling ratio and the ratio between the total excitation number and the ensemble size. The quantized field is found to produce asymmetric dynamics for symmetric initial conditions for both Rabi and Josephson oscillations.
