# Passing quantum correlations to qubits using any two-mode state

@article{Paternostro2009PassingQC, title={Passing quantum correlations to qubits using any two-mode state}, author={Mauro Paternostro and Gerardo Adesso and Steve Campbell}, journal={Physical Review A}, year={2009}, volume={80}, pages={062318} }

We draw an explicit connection between the statistical properties of an entangled two-mode continuous variable (CV) resource and the amount of entanglement that can be dynamically transferred to a pair of noninteracting two-level systems. More specifically, we rigorously reformulate entanglement-transfer process by making use of covariance matrix formalism. When the resource state is Gaussian, our method makes the approach to the transfer of quantum correlations much more flexible than in…

The transfer of entanglement from optical fields to qubits provides a viable approach to entangling remote qubits in a quantum network. In cavity quantum electrodynamics, the scheme relies on the…

### Continuous Variables Approach to Entanglement Creation and Processing

- Physics
- 2010

The continuous variable approach to study entangled dynamics of coupled harmonic oscillators interacting with a thermal reservoir and to a deterministic creation of entanglement in an atomic ensemble located inside a high-Q ring cavity finds that the entangling can persists for long times due to presence of constants of motion for the covariance matrix elements.
