Franson-Interferometric Bounds on Entangled Two-Photon Absorption
Albin Hedse, Sankaran Ramesh, Luis Matheis +7
Entangled photons offer quantum correlations with no classical analogue. In entangled pair two-photon absorption (ETPA), absorption rate is predicted to scale linearly rather than…
Towards Stirling cooler operable single-photon sources based on low-noise GaAs quantum dots
Maximilian Aigner, Jana Schlücking, Eva Schöll +15
For photonic quantum technology applications, sources capable of emitting photons with indistinguishability close to unity are essential. Ideally, these sources should not require…
Photonic hyperentanglement in polarisation and frequency via joint spectrum shaping
Tommaso Faleo, Fabian Steinhauser, Gregor Weihs +2
Hyperentanglement offers enhanced capacity for quantum information processing and communication protocols, especially in combination with robust high-dimensional degrees of freedom…
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…

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…
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…

Patrick Mark, Sebastian Gstir, Julian Münzberg +2
We measure the nonlinearity of a telecom-wavelength superconducting nanowire single-photon detector via incoherent beam combination. At typical photon count rates and detector bias…
Towards Photon-Number-Encoded High-dimensional Entanglement from a Sequentially Excited Quantum Three-Level System
Daniel A. Vajner, Nils D. Kewitz, Martin von Helversen +9
The sequential resonant excitation of a 2-level quantum system results in the emission of a state of light showing time-entanglement encoded in the photon-number-basis - notions th…
Theory of time-bin entangled photons from quantum emitters
Thomas K. Bracht, Florian Kappe, Moritz Cygorek +6
Entangled photon pairs form the foundation for many applications in the realm of quantum communication. For fiber-optic transfer of entangled photon pairs, time-bin encoding can po…
Keeping the photon in the dark: Enabling full quantum dot control by chirped pulses and magnetic fields
Florian Kappe, René Schwarz, Yusuf Karli +6
Because dark excitons in quantum dots are not directly optically accessible, so far they have not played a significant role in using quantum dots for photon generation. They posses…
Entanglement-induced collective many-body interference
Tommaso Faleo, Eric Brunner, Jonathan W. Webb +8
Entanglement and interference are both hallmark effects of quantum physics. Particularly rich dynamics arise when multiple (at least partially) indistinguishable particles are subj…
