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…
High Harmonic Spectroscopy Probes Lattice Dynamics
Jicai Zhang, Ziwen Wang, Frank Lengers +5
The probing of coherent lattice vibrations in solids has been conventionally carried out using time-resolved transient spectroscopy where only the relative oscillation amplitude ca…
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…
Structural symmetry-breaking to explain radiative Auger transitions in self-assembled quantum dots
Krzysztof Gawarecki, Clemens Spinnler, Liang Zhai +6
The optical spectrum of a quantum dot is typically dominated by the fundamental transition between the lowest-energy configurations. However, the radiative Auger process can result…
Multiple Rabi rotations of trions in InGaAs quantum dots observed by photon echo spectroscopy with spatially shaped laser pulses
S. Grisard, H. Rose, A. V. Trifonov +9
We study Rabi rotations arising in intensity-dependent photon echoes from an ensemble of self-assembled InGaAs quantum dots. To achieve a uniform distribution of intensities within…
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…
