  Quantum optical phenomena are explored in artificial atoms well known as
semiconductor quantum dots, in the presence of excitons and biexcitons. The
analytical results are obtained using the conventional time-dependent
perturbation technique. Numerical estimations are made for arealistic sample of
CdS quantum dots in a high-Q cavity. Quantum optical phenomena such as quantum
Rabi oscillations, photon statistics and collapse and revival of population
inversion in exciton and biexciton states are observed. In the presence of
biexcitons the collapse and revival phenomenon becomes faster due to the strong
coupling of biexciton with cavity field.
