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…
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…
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…
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…
