Towards coherent optical control of a single hole spin: Rabi rotation of a trion conditional on the spin state of the hole
A. J. Ramsay, S. J. Boyle, T. M. Godden +8
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 p…
Two qubit conditional quantum logic operation in a single self-assembled quantum dot
S. J. Boyle, A. J. Ramsay, F. Bello +4
The four-level exciton/biexciton system of a single semiconductor quantum dot acts as a two qubit register. We experimentally demonstrate an exciton-biexciton Rabi rotation conditi…
Intersublevel Polaron Dephasing in Self-Assembled Quantum Dots
E. A. Zibik, T. Grange, B. A. Carpenter +9
Polaron dephasing processes are investigated in InAs/GaAs dots using far-infrared transient four wave mixing (FWM) spectroscopy. We observe an oscillatory behaviour in the FWM sign…
Fast optical preparation, control and read-out of single quantum dot spin
A. J. Ramsay, S. J. Boyle, R. S. Kolodka +6
We propose and demonstrate the sequential initialization, optical control, and read-out of a single spin trapped in a semiconductor quantum dot. Hole spin preparation is achieved t…
Single-photon nonlinearity of a semiconductor quantum dot in a cavity
D. Sanvitto, F. P. Laussy, F. Bello +6
A single atom in a cavity is the model system of cavity quantum electrodynamics (CQED). The strong coupling regime between the atom and cavity-confined photon corresponds to the re…
Anomalous Stark Shifts in Single Vertically Coupled Pairs of InGaAs Quantum Dots
R. Oulton, A. I. Tartakovskii, A. Ebbens +4
Vertically coupled Stranski Krastanow QDs are predicted to exhibit strong tunnelling interactions that lead to the formation of hybridised states. We report the results of investig…
