Optimised spectral purity of unfiltered photons via pump and nonlinearity shaping
Tommaso Faleo, Christopher L. Morrison, Roméo Beignon +6
Photonic quantum technologies rely on the efficient generation and interference of indistinguishable photons. Exceptional achievements in this respect have been obtained by domain…
How to measure laser chirp rate at single-emitter excitation energies
Timothée Mounier, Moritz Kaiser, Mert Tuncel +8
We present a simple and direct method for measuring laser chirp rate, i.e., group delay dispersion (GDD) of ultrashort laser pulses at power levels compatible with single-quantum-e…
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…
Selective Preparation of Collective States in Coupled Quantum Emitters Using the SUPER Excitation Scheme
Johannes Kerber, Laurin Ostermann, Vikas Remesh +2
The efficient preparation of collective eigenstates of subwavelength-spaced optical dipoles is a prerequisite for observing their signature radiative properties and for their appli…
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…
Passive Demultiplexed Two-photon State Generation from a Quantum Dot
Yusuf Karli, Iker Avila Arenas, Christian Schimpf +11
High-purity multi-photon states are essential for photonic quantum computing. Among existing platforms, semiconductor quantum dots offer a promising route to scalable and determini…
