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…
Generation and manipulation of photon number wave packets in photonic cavities
Luca Nimmesgern, Moritz Cygorek, Doris E. Reiter +1
Quantum emitters inside optical cavities can create not only fixed photon number states but also photon number wave packets, which are states with a finite photon number distributi…
Few-Photon SUPER: Quantum emitter inversion via two off-resonant photon modes
Quentin W. Richter, Jan M. Kaspari, Thomas K. Bracht +4
With the realization of controlled quantum systems, exploring excitations beyond the resonant case opens new possibilities. We investigate an extended Jaynes-Cummings model where t…
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…
Multiple wave packets running in the photon number-space
Luca Nimmesgern, Moritz Cygorek, Adam Mielnik-Pyszczorski +3
If a two-level system coupled to a single-mode cavity is strongly driven by an external laser, instead of a continuous accumulation of photons in the cavity, oscillations in the me…
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…
