Quantum entanglement between a nonlinear nanomechanical resonator and a microwave field
Quantum entanglement nonlinear nanomechanical resonator microwave field
2010/11/11
We consider a theoretical model for a nonlinear nanomechanical resonator coupled to a superconducting microwave resonator. The nanomechanical resonator is driven parametrically at twice its resonance ...
Entanglement entropy between two coupled Tomonaga-Luttinger liquids
Entanglement entropy coupled Tomonaga-Luttinger liquids
2010/10/27
We consider a system of two coupled Tomonaga-Luttinger liquids (TLL) on parallel chains and
study the R´enyi entanglement entropy Sn between the two chains. The limit n ! 1 corresponds
to the ...
Three qubits in a symmetric environment: dissipatively generated asymptotic entanglement
Three qubits symmetric environment asymptotic entanglement
2010/10/18
We study the asymptotic entanglement of three identical qubits under the action of a Markovian open system dynamics that does not distinguish them.We show that by adding a completely depolarized qubit...
Spatial multipartite entanglement and localization of entanglement
localization of entanglement electromagnetic field
2010/3/10
We present a simple model together with its physical implementation which allows one to generate multipartite entanglement between several spatial modes of the electromagnetic field. It is based on pa...
