Photon Number Coherence of a Quantum Dot-Cavity System Excited Using the SUPER Scheme
Paul C. A. Hagen, Thomas Bracht, Mathieu Bozzio +4
To fulfill the security requirements of quantum cryptography, photon number coherence (PNC) of single photon sources has recently become an important figure of merit. Quantum dots…
Temperature-independent almost perfect photon entanglement from quantum dots via the SUPER scheme
Thomas K. Bracht, Moritz Cygorek, Tim Seidelmann +2
Entangled photon pairs are essential for quantum communication technology. They can be generated on-demand by semiconductor quantum dots, but several mechanisms are known to reduce…
Controlling the Photon Number Coherence of Solid-state Quantum Light Sources for Quantum Cryptography
Yusuf Karli, Daniel A. Vajner, Florian Kappe +14
Quantum communication networks rely on quantum cryptographic protocols including quantum key distribution (QKD) using single photons. A critical element regarding the security of Q…
Signatures of dynamically dressed states
Katarina Boos, Sang Kyu Kim, Thomas Bracht +10
The interaction of a resonant light field with a quantum two-level system is of key interest both for fundamental quantum optics and quantum technological applications employing re…
Beyond the four-level model: Dark and hot states in quantum dots degrade photonic entanglement
Barbara Ursula Lehner, Tim Seidelmann, Gabriel Undeutsch +9
Entangled photon pairs are essential for a multitude of photonic quantum applications. To date, the best performing solid-state quantum emitters of entangled photons are semiconduc…
Dressed-state analysis of two-color excitation schemes
Thomas K. Bracht, Tim Seidelmann, Yusuf Karli +5
To coherently control a few-level quantum emitter, typically pulses with an energy resonant to the transition energy are applied making use of the Rabi mechanism, while a single of…
