Measurement of the quantum-confined Stark effect in quantum dots with p-doped quantum dot barriers
Joe Mahoney, Mingchu Tang, Huiyun Liu +1
The quantum-confined Stark effect in InAs/In(Ga)As quantum dots (QDs) using non-intentionally doped and p-doped QD barriers was investigated to compare their performance for use in…
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…
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…
Long nuclear spin decay times controlled by optical pumping in individual quantum dots
M. N. Makhonin, A. I. Tartakovskii, I. Drouzas +8
Nuclear polarization dynamics are measured in the nuclear spin bi-stability regime in a single optically pumped InGaAs/GaAs quantum dot. The controlling role of nuclear spin diffus…
Nuclear Spin Switch in Semiconductor Quantum Dots
A. I. Tartakovskii, T. Wright, A. Russell +10
We show that by illuminating an InGaAs/GaAs self-assembled quantum dot with circularly polarized light, the nuclei of atoms constituting the dot can be driven into a bistable regim…
