Swing-up of quantum emitter population using detuned pulses
Thomas K. Bracht, Michael Cosacchi, Tim Seidelmann +5
The controlled preparation of the excited state in a quantum emitter is a prerequisite for its usage as single-photon sources - a key building block for quantum technologies. In th…
Deterministic photon storage and readout in a semimagnetic quantum-dot--cavity system doped with a single Mn ion
M. Cosacchi, T. Seidelmann, A. Mielnik-Pyszczorski +6
Light trapping is a crucial mechanism for synchronization in optical communication. Especially on the level of single photons, control of the exact emission time is desirable. In t…
-photon bundle statistics in different solid-state platforms
M. Cosacchi, A. Mielnik-Pyszczorski, T. Seidelmann +4
The term -photon bundles has been coined for a specific type of photon emission, where light quanta are released from a cavity only in groups of particles. This emission lea…
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…
Time-dependent switching of the photon entanglement type using a driven quantum emitter-cavity system
Tim Seidelmann, Doris E. Reiter, Michael Cosacchi +3
The cascaded decay in a four-level quantum emitter is a well established mechanism to generate polarization entangled photon pairs, the building blocks of many applications in quan…
Accuracy of the quantum regression theorem for photon emission from a quantum dot
M. Cosacchi, T. Seidelmann, M. Cygorek +3
The quantum regression theorem (QRT) is the most-widely used tool for calculating multitime correlation functions for the assessment of quantum emitters. It is an approximate metho…
