We perform a review of various approaches to the implementation of quantum memories,
with an emphasis on activities within the quantum memory sub-project of the EU integrated …

The mesoscopic spin system formed by the 10 4–10 6 nuclear spins in a semiconductor
quantum dot offers a unique setting for the study of many-body spin physics in the …

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 regime …

We present measurements of the buildup and decay of nuclear spin polarization in a single
semiconductor quantum dot. Our experiment shows that we polarize the nuclei in a few …

Combining external control with long spin lifetime and coherence is a key challenge for solid
state spin qubits. Tunnel coupling with electron Fermi reservoir provides robust charge state …

We show that optical pum** of electron spins in individual InGaAs quantum dots leads to
strong nuclear polarization that we measure via the Overhauser shift δ n in …

The nuclear quadrupole interaction eliminates the restrictions imposed by hyperfine
interaction on the spin coherence of an electron and nuclei in a quantum dot. The strain …

We present an ultrahigh resolution Raman study of the lifetime of 1 THz acoustic phonons
confined in nanocavities. We demonstrate that the cavity Q factor can be controlled by …

The spin dynamics of strongly localized donor-bound electrons in fluorine-doped ZnSe
epilayers is studied using pump-probe Kerr rotation techniques. A method exploiting the …

Charged quantum dots provide an important platform for a range of emerging quantum
technologies. Colloidal quantum dots in particular offer unique advantages for such …
