We explore the antiresonance phenomenon, where a two-level atom is excited inside a single-mode, laser-driven cavity without appreciably exciting the field mode. Antiresonance is well known in classical physics and the excitation of the atomic and field degrees of freedom by a weak laser field can be easily understood in a classical oscillator picture. The temporal intensity correlations in the signal emitted from the atom and from the cavity, however, show strong signs of nonclassical behavior. We calculate these correlations and show how they can be interpreted in terms of a conditional quantum trajectory dynamics of the system.
