Optical and magnetic response by design in GaAs quantum dots
Christian Schimpf, Ailton J. Garcia, Zhe X. Koong +24
Quantum networking technologies use spin qubits and their interface to single photons as core components of a network node. This necessitates the ability to co-design the magnetic-…
Fast optical control of a coherent hole spin in a microcavity
Mark Hogg, Nadia Antoniadis, Malwina Marczak +8
A spin-photon interface is one of the key components of a quantum network. Physical platforms under investigation span the range of modern experimental physics, from ultra-cold ato…
A quantum dot coupled to a suspended-beam mechanical resonator: from the unresolved- to the resolved-sideband regime
Clemens Spinnler, Giang N. Nguyen, Ying Wang +9
We present experiments in which self-assembled InAs quantum dots are coupled to a thin, suspended-beam GaAs resonator. The quantum dots are driven resonantly and the resonance fluo…
A single-photon emitter coupled to a phononic-crystal resonator in the resolved-sideband regime
Clemens Spinnler, Giang N. Nguyen, Ying Wang +9
A promising route towards the heralded creation and annihilation of single-phonons is to couple a single-photon emitter to a mechanical resonator. The challenge lies in reaching th…
Enhanced Electron Spin Coherence in a GaAs Quantum Emitter
Giang N. Nguyen, Clemens Spinnler, Mark R. Hogg +10
A spin-photon interface should operate with both coherent photons and a coherent spin to enable cluster-state generation and entanglement distribution. In high-quality devices, sel…
Structural symmetry-breaking to explain radiative Auger transitions in self-assembled quantum dots
Krzysztof Gawarecki, Clemens Spinnler, Liang Zhai +6
The optical spectrum of a quantum dot is typically dominated by the fundamental transition between the lowest-energy configurations. However, the radiative Auger process can result…
Quantum Interference of Identical Photons from Remote GaAs Quantum Dots
Liang Zhai, Giang N. Nguyen, Clemens Spinnler +6
Photonic quantum technology provides a viable route to quantum communication, quantum simulation, and quantum information processing. Recent progress has seen the realisation of bo…
Optically driving the radiative Auger transition
Clemens Spinnler, Liang Zhai, Giang N. Nguyen +8
In a radiative Auger process, optical decay is accompanied by simultaneous excitation of other carriers. The radiative Auger process gives rise to weak red-shifted satellite peaks…
Influence of molecular beam effusion cell quality on optical and electrical properties of quantum dots and quantum wells
G. N. Nguyen, A. R. Korsch, M. Schmidt +7
Quantum dot heterostructures with excellent low-noise properties became possible with high purity materials recently. We present a study on molecular beam epitaxy grown quantum wel…
Low-Noise GaAs Quantum Dots for Quantum Photonics
Liang Zhai, Matthias C. Löbl, Giang N. Nguyen +6
Quantum dots are both excellent single-photon sources and hosts for single spins. This combination enables the deterministic generation of Raman-photons -- bandwidth-matched to an…
Radiative Auger Process in the Single-Photon Limit
Matthias C. Löbl, Clemens Spinnler, Alisa Javadi +8
In a multi-electron atom, an excited electron can decay by emitting a photon. Typically, the leftover electrons are in their ground state. In a radiative Auger process, the leftove…
