Title: Resonant excitation of semiconductor quantum dots for the
generation of non-classical states of light
Location: Computer Science Department, room A115 (ground floor), Voutes
Time: 16:00
Language: English
Abstract
Recent developments in quantum information need coherent manipulation
of quantum states. Among solid-state systems, semiconductor quantum
dots are promising candidates for realizing qubits. Important
advantages are the three dimensional confinement leading to a discrete
energy spectrum and the possible integration of dots in specific
devices. In this presentation, I will show how with resonant optical
pulses we can prepare and manipulate the states, and obtain single
indistinguishable photons. I will also address the problem of
interactions with the solid environment (phonons, fluctuating charges)
of the quantum dots that may cause severe limitations in the quantum
coherence.
