Cavity-quantum electrodynamics with quantum dots

Alper Kıraz, C. Reese, B. Gayral +6 more

Semiconductor quantum dots (QDs) have emerged as promising candidates for studying quantum optical phenomena. In particular, cavity-quantum electrodynamics effects can be investigated using a single QD embedded inside a photonic nanostructure, where both the carriers and photons are confined within sub-micron length scales in all three dimensions. Since QD location inside the cavity is fixed by the growth, this system is free of the stringent trapping requirements that limit its atomic counterpart. The possibility of fabricating photonic nanostructures with ultra-small optical-mode volumes and long photon lifetimes enhances the prospects for applications in quantum information processing.

Exploiting coherent light-matter interactions in semiconductor quantum dot — Cavity systems

Stephen Hughes, Pradyumna K. Pathak, H. J. Carmichael

We discuss the prospects of exploiting coherently driven light-matter interactions in semiconductor quantum dot - cavity systems. Regimes of pulse-triggered single photons and steady-state exciton inversion are introduced, and a connection to recent experiments with planar photonic crystals and micropillar cavities is made.

Cavity quantum electrodynamics with quantum dots in microcavities

Jan Gudat

This thesis presents a viable route towards the implementation of quantum computing utilizing quantum dots embedded in optical microcavities. Following the introduction of the big picture and long-term visionary goal, general concepts fundamental to this field of research are described: quantum dots and microcavities, forming the physical system explored; and cavity quantum electrodynamics, the theoretical language used to describe their interaction.\n\nThe physical structure and the optical mode composition in oxide-apertured micropillar cavities is analyzed. Permanent tuning methods achieving polarization degenerate cavities resonant with a quantum dot transition are illustrated. Active positioning of single quantum dots is developed providing an accuracy suitable to measure the interaction between a quantum dot and a cavity in the strong coupling limit. The possibility to waveguide-couple photonic crystal cavities on the same sample is explored. A theoretical description of the quantum-dot confined electron dynamics is presented. \nPresented are ideas how a hybrid quantum system could serve for implementation of a controlled NOT gate, and therewith be the building block for a quantum computer, exploiting the weak coupling regime. A Bell-state analyzer is the second scheme that is discussed. \nResults from reflection spectroscopy measurements on single quantum dots in a micropillar cavity are presented.
