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…
Coherent Dynamics in Quantum Emitters under Dichromatic Excitation
Z. X. Koong, E. Scerri, M. Rambach +8
We characterize the coherent dynamics of a two-level quantum emitter driven by a pair of symmetrically-detuned phase-locked pulses. The promise of dichromatic excitation is to spec…
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…
Valley and spin polarized broken symmetry states of interacting electrons in gated MoS quantum dots
Ludmila Szulakowska, Moritz Cygorek, Maciej Bieniek +1
Understanding strongly interacting electrons enables the design of materials, nanostructures and devices. Developing this understanding relies on the ability to tune and control el…
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…
Accurate and efficient description of interacting carriers in quantum nanostructures by selected configuration interaction and perturbation theory
Moritz Cygorek, Matthew Otten, Marek Korkusinski +1
We present a method to calculate many-body states of interacting carriers in million atom quantum nanostructures based on atomistic tight-binding calculations and a combination of…
