Quantum simulator of extended bipartite Hubbard model with broken sublattice symmetry: magnetism, correlations, and phase transitions
Yasser Saleem, Amintor Dusko, Moritz Cygorek +2
We describe here a quantum simulator of extended bipartite Hubbard model with broken sublattice symmetry. The simulator consists of a structured lateral gate confining two dimensio…
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…
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…
