Schrödinger cats in quantum-dot--cavity systems
M. Cosacchi, T. Seidelmann, J. Wiercinski +4
A Schrödinger-cat state is a coherent superposition of macroscopically distinguishable quantum states, in quantum optics usually realized as superposition of coherent states. Proto…
Different types of photon entanglement from a constantly driven quantum emitter inside a cavity
Tim Seidelmann, Michael Cosacchi, Moritz Cygorek +3
Bell states are the most prominent maximally entangled photon states. In a typical four-level emitter, like a semiconductor quantum dot, the photon states exhibit only one type of…
On-demand generation of higher-order Fock states in quantum-dot--cavity systems
M. Cosacchi, J. Wiercinski, T. Seidelmann +4
The on-demand preparation of higher-order Fock states is of fundamental importance in quantum information sciences. We propose and compare different protocols to generate higher-or…
Transiently changing shape of the photon number distribution in a quantum-dot--cavity system driven by chirped laser pulses
M. Cosacchi, T. Seidelmann, F. Ungar +3
We have simulated the time evolution of the photon number distribution in a semiconductor quantum dot-microcavity system driven by chirped laser pulses and compare with unchirped r…
