Exciton and biexciton preparation via coherent swing-up excitation in a GaAs quantum dot embedded in micropillar cavity
Claudia Piccinini, Aleksander Rodek, Abdulmalik A. Madigawa +9
Coherent control of quantum emitters is essential for scalable quantum photonic technologies. The recently proposed swing-up of quantum emitter (SUPER) scheme allows efficient and…
Theory of single-photon emission from neutral and charged excitons in a polarization-selective cavity
Luca Vannucci, Niels Gregersen
Single-photon sources based on neutral or charged excitons in a semiconductor quantum dot are attractive resources for photonic quantum computers and simulators. To obtain indistin…
Photonic "hourglass" design beyond the standard bulk model of phonon decoherence
José Ferreira Neto, Benedek Gaál, Luca Vannucci +1
We study the impact of mechanical vibrations on the performance of the photonic "hourglass" structure, which is predicted to emit single photons on-demand with near-unity efficienc…
One-dimensional photonic wire as a single-photon source: Implications of cavity QED to a phonon bath of reduced dimensionality
José Ferreira Neto, Matias Bundgaard-Nielsen, Niels Gregersen +1
While the semiconductor quantum dot placed in a solid-state material allows for deterministic emission of single photons, the photon indistinguishability is strongly influenced by…
SUPER excitation of quantum emitters is a multi-photon process
Luca Vannucci, Niels Gregersen
The swing-up of quantum emitter population (SUPER) scheme allows to populate the excited state of a quantum emitter with near-unity fidelity using two red-detuned laser pulses. Its…
High-purity and stable single-photon emission in bilayer WSe via phonon-assisted excitation
Claudia Piccinini, Athanasios Paralikis, José Ferreira Neto +6
The excitation scheme is essential for single-photon sources, as it governs exciton preparation, decay dynamics, and the spectral diffusion of emitted photons. While phonon-assiste…
