Decay and storage of multiparticle entangled states of atoms in collective thermostat
A. M. Basharov, V. N. Gorbachev, A. A. Rodichkina
We derive a master equation describing the collective decay of two-level atoms inside a single mode cavity in the dispersive limit. By considering atomic decay in the collective th…
Quantum channel for light based on integrals of motion
V. N. Gorbachev, A. I. Trubilko
A method based on integrals of motion for collective processes has been introduced to achieve physical schemes in which one of the systems is insensitive to interaction. Decoherenc…
On Multiparticle Entanglement via Resonant Interaction between Light and atomic Ensembles
V. N. Gorbachev, A. I. Trubilko
Multiparticle entangled states generated via interaction between narrow-band light and an ensemble of identical two-level atoms are considered. Depending on the initial photon stat…
On multiparticle W states, their implementations and applications in quantum information problems
V. N. Gorbachev, A. I. Trubilko
Large number of multimode entangled states of light generated in down conversion processes belongs to a collection which is natural generalization of the W class. A brief overview…
On parametric type interaction between light and atomic ensembles
V. N. Gorbachev, A. I. Zhiliba, A. A. Rodichkina +1
One-photon and Raman type interactions between two-level atoms and narrow-band light are considered. We give some exactly solvable models of these processes when only one-photon Fo…
On amplification of light in the continuous EPR state
V. N. Gorbachev, A. I. Trubilko
Two schemes of amplification of two-mode squeezed light in the continuous variable EPR-state are considered. They are based on the integrals of motion, which allow conserving quant…
On preparation of the W-states from atomic ensembles
V. N. Gorbachev, A. A. Rodichkina, A. I. Trubilko
A scheme, where three atomic ensembles can be prepared in the states of the W-class via Raman type interaction of strong classical field and a projection measurement involved three…
Dense coding and safety of quantum communications
A. Ya. Kazakov
The sending station being the classical device can be eavesdropped by classical means. Dense coding and quantum nature of wave function give the additional resource to raise the sa…
Can the states of the W-class be suitable for teleportation
V. N. Gorbachev, A. I. Trubilko, A. A. Rodichkina
Entangled states of the W-class are considered as a quantum channel for teleportation or the states to be sent. The protocols have been found by unitary transformation of the schem…
