Reinforcement learning has been widely used in many problems, including quantum control
of qubits. However, such problems can, at the same time, be solved by traditional, non …

The role of quantum confinement (QC) in Si and Ge nanostructures (NSs) including quantum
dots, quantum wires, and quantum wells is assessed under a wide variety of fabrication …

Analytical solutions to the time-dependent Schrödinger equation describing a driven two-
level system are invaluable to many areas of physics, but they are also extremely rare. Here …

Pulsed resonant fluorescence is used to probe ultrafast phonon-assisted exciton and
biexciton preparation in individual self-assembled InGaAs quantum dots. By driving the …

We demonstrate that the quantum dot-confined dark exciton forms a long-lived integer spin
solid-state qubit that can be deterministically on-demand initiated in a pure state by one …

Coherent quantum control and resonance fluorescence of few-level quantum systems is
integral for quantum technologies. Here we perform resonance and near-resonance …

We perform full time-resolved tomographic measurements of the polarization state of pairs of
photons emitted during the radiative cascade of the confined biexciton in a semiconductor …

We study the potential for controlled population inversion in a coupled system comprised of
a semiconductor quantum dot and a metal nanoparticle. We show that the widely used …

A simple algorithm is presented based on a type of partial reverse engineering that
generates an unlimited number of exact analytical solutions to the Schrödinger equation for …

Quantum dots are arguably the best interface between matter spin qubits and flying photonic
qubits. Using quantum dot devices to produce joint spin-photonic states requires the …
