Dynamical suppression of fluctuations in an interacting nuclear spin bath of a self-assembled quantum dot using multiple pulse nuclear magnetic resonance
A. M. Waeber, M. Hopkinson, M. S. Skolnick +1
Electron spin qubit coherence in quantum dots is ultimately limited by random nuclear spin bath fluctuations. Here we aim to eliminate this randomness by making spin bath evolution…
Quadrupolar induced suppression of nuclear spin bath fluctuations in self-assembled quantum dots
E. A. Chekhovich, M. Hopkinson, M. S. Skolnick +1
Decoherence in quantum logic gates (qubits) due to interaction with the surrounding environment is a major obstacle to the practical realization of quantum information technologies…
Dynamic nuclear polarization in InGaAs/GaAs and GaAs/AlGaAs quantum dots under non-resonant ultra-low power optical excitation
J. Puebla, E. A. Chekhovich, M. Hopkinson +4
We study experimentally the dependence of dynamic nuclear spin polarization on the power of non-resonant optical excitation in two types of individual neutral semiconductor quantum…
High resolution nuclear magnetic resonance spectroscopy of highly-strained quantum dot nanostructures
E. A. Chekhovich, K. V. Kavokin, J. Puebla +7
Much new solid state technology for single-photon sources, detectors, photovoltaics and quantum computation relies on the fabrication of strained semiconductor nanostructures. Succ…
Polariton states bound to defects in GaAs/AlAs planar microcavities
Joanna M Zajac, Wolfgang Langbein, Maxime Hugues +1
We report on polariton states bound to defects in planar GaAs/AlAs microcavities grown by molecular beam epitaxy. The defect types relevant for the spatial polariton dynamics in th…
Isotope sensitive measurement of the hole-nuclear spin interaction in quantum dots
E. A. Chekhovich, A. B. Krysa, M. Hopkinson +4
Decoherence caused by nuclear field fluctuations is a fundamental obstacle to the realization of quantum information processing using single electron spins. Alternative proposals h…
