Deviations from thermal light statistics in ensembles of independent two-level emitters
Manuel Bojer, André Cidrim, Romain Bachelard +1
We investigate the light statistics of an ensemble of independent motionless two-level atoms in a product state. We identify the conditions under which the cold atomic ensemble emi…
Coherent Control of Photon Correlations in Trapped Ion Crystals
K. Singh, A. Cidrim, A. Kovalenko +4
While the spontaneous emission from independent emitters provides spatially uncorrelated photons - a typical manifestation of quantum randomness, the interference of the coherent s…
Postselected Entangled States by Photon Detection
Pedro Rosario, A. Cidrim, R. Bachelard
Postselection is a non-deterministic mechanism to entangle subsystems, often used in weakly-excited systems. We here show how highly-excited ensembles of two-level emitters can be…
Unraveling Dicke Superradiant Decay with Separable Coherent Spin States
Pedro Rosario, Luiz O. R. Solak, A. Cidrim +2
We show that idealized Dicke superradiant decay from a fully inverted state can at all times be described by a positive statistical mixture of coherent spin states (CSS). Since CSS…
Light Statistics from Large Ensembles of Independent Two-level Emitters: Classical or Non-classical?
M. Bojer, A. Cidrim, P. P. Abrantes +2
We investigate the photon statistics of an ensemble of coherently driven non-interacting two-level atoms in the weak driving regime. As it turns out, the system displays unique emi…
Detecting entanglement from macroscopic measurements of the electric field and its fluctuations
Pedro Rosario, Alan C. Santos, Nicola Piovella +3
To address the outstanding task of detecting entanglement in large quantum systems, entanglement witnesses have emerged, addressing the separable nature of a state. Yet optimizing…
