Parametric resonant enhancement of motional entanglement under optimal control: an analytical study
Gad Horovitz, Alexander N. Poddubny
We study theoretically continuous-variable entanglement between the motional degrees of freedom of optically trapped massive particles coupled via the Coulomb interaction, in the p…

Nonequilibrium entanglement between levitated masses under optimal control
Alexander N. Poddubny, Klemens Winkler, Benjamin A. Stickler +3
We present a protocol that maximizes unconditional entanglement generation between two masses interacting directly through potential. The protocol combines optimal quantu…

How single-photon nonlinearity is quenched with multiple quantum emitters: Quantum Zeno effect in collective interactions with -level atoms
Alexander N. Poddubny, Serge Rosenblum, Barak Dayan
Single-photon nonlinearity, namely the change in the response of the system as the result of the interaction with a single photon, is generally considered an inherent property of a…
