Creating a switchable optical cavity with controllable quantum-state mapping between two modes
Grzegorz Chimczak, Karol Bartkiewicz, Zbigniew Ficek +1
We describe how an ensemble of four-level atoms in the diamond-type configuration can be applied to create a fully controllable effective coupling between two cavity modes. The dia…
Generation of discrete superpositions of coherent states in the anharmonic oscillator model
A. Miranowicz, R. Tanas, S. Kielich
The problem of generating discrete superpositions of coherent states in the process of light propagation through a nonlinear Kerr medium, which is modelled by the anharmonic oscill…
Quantum phase properties of nonlinear optical phenomena
R. Tanas, A. Miranowicz, Ts. Gantsog
We review some quantum-phase descriptions of optical fields. We focus on real fields that can be generated in practice in various nonlinear optical processes. Thus, we rather avoid…
Two-photon dipole-dipole blockade
Khulud Almutairi, Ryszard Tanas, Zbigniew Ficek
We describe a mechanism for a controlled generation of a pure Bell state with correlated atoms that involve two or zero excitations. The mechanism inhibits transitions into singly…
Delayed (sudden) birth of entanglement
Z. Ficek, R. Tanas
The concept of time delayed creation of entanglement by the dissipative process of spontaneous emission is investigated. A threshold effect for the creation of entanglement is foun…
Dark periods and revivals of entanglement in a two qubit system
Z. Ficek, R. Tanas
In a recent paper Yu and Eberly [Phys. Rev. Lett. {\bf 93}, 140404 (2004)] have shown that two initially entangled and afterwards not interacting qubits can become completely disen…
