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…
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…
Single-photon emitters in WSe: Critical role of phonons on excitation schemes and indistinguishability
Luca Vannucci, José Ferreira Neto, Claudia Piccinini +3
Within optical quantum information processing, single-photon sources based on a two-level system in a semiconductor material allow for on-demand generation of single photons. To in…
