Evolution of Continuous Variable Entanglement and Discord in Open Quantum Systems
In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, we give a description of the continuous-variable quantum entanglement and quantum discord for a system consisting of two non-interacting modes embedded in a thermal environment. Entanglement and discord are used to quantify the quantum correlations of the system. For all values of the tempe...
متن کاملEntanglement in Open Quantum Systems
Quantum entanglement is considered to be a central resource of quantum information processing: entanglement is a key ingredient in quantum teleportation [1], and is used to perform conditional two-qubit operations, which are primordial for running a quantum algorithm [2]. There is a large body of literature on the abstract, rather mathematical theory of entanglement [3], of pure as well as of m...
متن کاملContinuous-Variable Triple-Photon States Quantum Entanglement.
We investigate the quantum entanglement of the three modes associated with the three-photon states obtained by triple-photon generation in a phase-matched third-order nonlinear optical interaction. Although the second-order processes have been extensively dealt with, there is no direct analogy between the second and third-order mechanisms. We show, for example, the absence of quantum entangleme...

متن کاملEntanglement and squeezingin continuous-variable systems
We introduce a multi-mode squeezing coefficient to characterize entanglement in N-partite continuous-variable systems. The coefficient relates to the squeezing of collective observables in the 2N-dimensional phase space and can be readily extracted from the covariance matrix. Simple extensions further permit to reveal entanglement within specific partitions of a multipartite system. Application...
