A Race Track Trapped-Ion Quantum Processor
S. A. Moses, C. H. Baldwin, M. S. Allman +93
We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion quantum computer based on a linear trap with periodic boundary conditions, which resembles a race t…
Exciton spin-flip rate in quantum dots determined by a modified local density of optical states
Jeppe Johansen, Brian Julsgaard, Søren Stobbe +2
The spin-flip rate that couples dark and bright excitons in self-assembled quantum dots is obtained from time-resolved spontaneous emission measurements in a modified local density…
Frequency dependence of the radiative decay rate of excitons in self-assembled quantum dots: experiment and theory
Søren Stobbe, Jeppe Johansen, Philip Trøst Kristensen +2
We analyze time-resolved spontaneous emission from excitons confined in self-assembled quantum dots placed at various distances to a semiconductor-air interface. Th…
Size dependent oscillator strength and quantum efficiency of CdSe quantum dots determined by controlling the local density of states
M. D. Leistikow, J. Johansen, A. J. Kettelarij +2
We study experimentally time-resolved emission of CdSe quantum dots in an environment with a controlled local density of states (LDOS). The decay rate is measured versus frequency…
Decay dynamics of quantum dots influenced by the local density of optical states of two-dimensional photonic crystal membranes
B. Julsgaard, J. Johansen, S. Stobbe +5
We have performed time-resolved spectroscopy on InAs quantum dot ensembles in photonic crystal membranes. The influence of the photonic crystal is investigated by varying the latti…
Size-Dependence of the Wavefunction of Self-Assembled Quantum Dots
J. Johansen, S. Stobbe, I. S. Nikolaev +5
The radiative and non-radiative decay rates of InAs quantum dots are measured by controlling the local density of optical states near an interface. From time-resolved measurements…
