We study optically driven Rabi rotations of a quantum dot exciton transition between 5 and 50 K, and for pulse-areas of up to $14\pi$. In a high driving field regime, the decay of the Rabi rotations is nonmonotonic, and the period decreases with puls

A two-photon absorption resonance is observed when the sum-frequency of two laser pulses equals the creation energy of a biexciton in a single InAs/GaAs semiconductor quantum dot. Resonant excitation of the two-color two-photon transition results in

A hole spin is a potential solid-state q-bit, that may be more robust against nuclear spin induced dephasing than an electron spin. Here we propose and demonstrate the sequential preparation, control and detection of a single hole spin trapped on a s

We present a two-colour photocurrent detection method for coherent control of a single InGaAs/GaAs self-assembled quantum dot. A pulse shaping technique provides a high degree of control over picosecond optical pulses. Rabi rotations on the exciton t

We report coherent optical control of a single hole spin confined to an InAs/GaAs quantum dot. The hole spin was initialized by fast dissociation of a spin-polarized electron-hole pair, and controlled by combining coherent rotations about two perpend

This thesis describes experiments on the initialisation, coherent control, and readout of a single hole spin trapped in a self assembled InGaAs semiconductor quantum dot. High fidelity initialisation of a hole spin state is achieved by the fast ionis

We demonstrate fast initialization of a single hole spin trapped in an InGaAs quantum dot with a fidelity F>99% and a 1/e time of ∼30 ps, by applying a magnetic field parallel to the growth direction. We show that the fidelity of the hole spin, pre

Intermediate-resolution spectra of a sample of symbiotic stars in the K and L bands have been obtained. In many objects, Pfund and Brackett emission lines are detected, as well as the first-overtone CO absorption bands. Synthetic spectra are used to

We report picosecond control of excitonic dressed states in a single semiconductor quantum dot. A strong laser pulse couples the exciton and biexciton states, to form an Autler-Townes doublet of the neutral exciton transition. The Rabi-splitting, and
