Transfer of optical vortices in coherently prepared media
Hamid Reza Hamedi, Julius Ruseckas, Emmanuel Paspalakis +1
We consider transfer of optical vortices between laser pulses carrying orbital angular momentum (OAM) in a cloud of cold atoms characterized by the configuration of the atom-li…
Efficient Generation of the Triplet Bell State Between Coupled Spins Using Transitionless Quantum Driving and Optimal Control
Dionisis Stefanatos, Emmanuel Paspalakis
We consider a pair of coupled spins with Ising interaction in z-direction and study the problem of generating efficiently the triplet Bell state. We initially analyze the transitio…
Boosting Entanglement Between Exciton-Polaritons with On-Off Switching of Josephson Coupling
Dionisis Stefanatos, Emmanuel Paspalakis
We show that the appropriate on-off switching of Josephson coupling between exciton-polaritons in coupled semiconductor microcavities can reveal the full capacity for generating en…
Efficient entanglement generation between exciton-polaritons using shortcuts to adiabaticity
Dionisis Stefanatos, Emmanuel Paspalakis
We use shortcuts to adiabaticity, a method introduced to speed up adiabatic quantum dynamics, for the efficient generation of entanglement between exciton-polaritons in coupled sem…
Maximizing entanglement in bosonic Josephson junctions using shortcuts to adiabaticity and optimal control
Dionisis Stefanatos, Emmanuel Paspalakis
In this article we consider a bosonic Josephson junction, a model system composed by two coupled nonlinear quantum oscillators which can be implemented in various physical contexts…
