Photon Number Coherence in Quantum Dot-Cavity Systems can be Enhanced by Phonons
Paul C. A. Hagen, Mathieu Bozzio, Moritz Cygorek +2
Semiconductor quantum dots are a versatile source of single photons with tunable properties to be used in quantum-cryptographic applications. A crucial figure of merit of the emitt…
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…
Two-photon excitation with finite pulses unlocks pure dephasing-induced degradation of entangled photons emitted by quantum dots
Tim Seidelmann, Thomas K. Bracht, Barbara Ursula Lehner +7
Semiconductor quantum dots have emerged as an especially promising platform for the generation of polarization-entangled photon pairs. However, it was demonstrated recently that th…
Phonon-induced transition between entangled and nonentangled photon emission in constantly driven quantum-dot--cavity systems
Tim Seidelmann, Michael Cosacchi, Moritz Cygorek +3
Entangled photon pairs are essential for many applications in quantum technologies. Recent theoretical studies demonstrated that different types of entangled Bell states can be cre…
SUPER Scheme in Action: Experimental Demonstration of Red-detuned Excitation of a Quantum Dot
Yusuf Karli, Florian Kappe, Vikas Remesh +8
The quest for the perfect single-photon source includes finding the optimal protocol for exciting the quantum emitter. Based on a recently proposed, so-called SUPER (swing-up of qu…
The optical Stark shift to control the dark exciton occupation of a quantum dot in a tilted magnetic field
Miriam Neumann, Florian Kappe, Thomas K. Bracht +5
When a detuned and strong laser pulse acts on an optical transition, a Stark shift of the corresponding energies occurs. We analyze how this optical Stark effect can be used to pre…
