The focus of our effort has been to develop quantum information processing technologies based on a solid-state cavity QED platform consisting of quantum dots in photonic crystals. The main goals that we have accomplished include 1. Study of the ultrafast dynamics of the quantum dot-cavity QED system Majumdar et al., Phys. Rev. A, 2012, and ultrafast switching between two single photon pulses mediated by the quantum dot-photonic crystal cavity QED system Englund et al., Phys. Rev. Letters, 2012 2. Probing the ladder of dressed states in the solid state cavity QED system Majumdar et al, Physical Review A, 2012 3. Study of the off-resonant quantum dot-cavity coupling in solid-state cavity QED system, and the phonon mediated off-resonant interaction between two quantum dots Majumdar et al., Physical Review B , 2012 4. Coherent optical spectroscopy of a single quantum dot via an off-Resonant cavity - much simpler than in conventional approaches Majumdar et al, Physical Review B, 2011 Papageorge et al., New. Journal of Physics, 2011 5. Study of the cavity QED with a quantum dot coupled to a photonic molecule Majumdar et al., Phys. Rev. B, 2012 6. Study of the effect of photo-generated carriers on the spectral diffusion of a quantum dot coupled to a photonic crystal cavity Majumdar et al., Physical Review B, 2011.
