Quantum and classical information processing with a single quantum dot in photonic crystal cavity

Quantum dots (QDs) coupled to photonic crystal cavities are interesting both as a testbed for fundamental cavity quantum electrodynamics (CQED) experiments, as well as nano-scale devices for optical quantum and classical information processing. In addition to providing a scalable, robust, on-chip, semiconductor platform, this coupled system also enables very large dipole-field interaction strength, as a result of the field localization inside of sub-cubic wavelength volume (vacuum Rabi frequency is in the range of 10s of GHz). In this paper, we describe some of the recent experiments performed on this system in our group.
