We study experimentally and theoretically the in-plane magnetic field dependence of the coupling between dots forming a vertically stacked double dot molecule. The InAsP molecule is grown epitaxially in an InP nanowire and interrogated optically at millikelvin temperatures. The strength of interdot tunneling, leading to the formation of the bonding-antibonding pair of molecular orbitals, is investigated by adjusting the sample geometry. For specific geometries, we show that the interdot… Expand

Orbital Tuning of Tunnel Coupling in InAs/InP Nanowire Quantum Dots
A qualitatively different regime is observed at relatively low filling numbers, where tunneling rates are rather controlled by the axial configuration of the electron orbital, and the barrier transparency for the various orbitals is found to evolve as expected from numerical simulations. Expand
Atomistic theory of electronic and optical properties of InAsP/InP nanowire quantum dots
We present here an atomistic theory of the electronic and optical properties of hexagonal InAsP quantum dots in InP nanowires in the wurtzite phase. These self-assembled quantum dots are unique inExpand
Highly symmetric and tunable tunnel couplings in InAs/InP nanowire heterostructure quantum dots.
The results demonstrate that integrated InAs/InP QDs provide a promising platform for electron tunneling spectroscopy in InAs nanowires, which can readily be contacted by a variety of superconducting materials to investigate subgap states in proximitized NW regions, or be used to characterize thermoelectric nanoscale devices in the quantum regime.

Individually addressable double quantum dots formed with nanowire polytypes and identified by epitaxial markers
Double quantum dots (DQDs) hold great promise as building blocks for quantum technology as they allow for two electronic states to coherently couple. Defining QDs with materials rather than usingExpand
Nanowire-based sources of non-classical light.
State-of-the-art nanowire sources are compared to other solid-state quantum emitter platforms with regard to the key metrics of single photon purity, indistinguishability and entangled-pair fidelity to maximally entangled Bell states. Expand
Proposed Scheme to Generate Bright Entangled Photon Pairs by Application of a Quadrupole Field to a Single Quantum Dot.
This work shows that the quadrupole electric field corrects for the spatial asymmetry of the excitonic wave function for any quantum dot dipole orientation and fully erases the fine-structure splitting without compromising the spatial overlap between electrons and holes. Expand
Scalable in operando strain tuning in nanophotonic waveguides enabling three-quantum-dot superradiance
Local tuning of quantum dots embedded in a photonic waveguide can be achieved through the strain produced by laser heating of a thin layer of HfO2 deposited around the waveguide and the method is exploited to tune three quantum dots in resonance. Expand
Theory and experiments of coherent photon coupling in semiconductor nanowire waveguides with quantum dot molecules
