Systematic construction of genuine-multipartite-entanglement criteria in continuous-variable systems using uncertainty relations

2015 · Physical Review A

A general procedure to construct criteria for identifying genuine multipartite continuous-variable entanglement is presented. It relies on the definition of adequate global operators describing the multipartite system, the positive partial transpose criterion of separability, and …

Unified framework to determine Gaussian states in continuous-variable systems

2017 · Physical Review A

Gaussian states are the backbone of quantum information protocols with continuous-variable systems whose power relies fundamentally on the entanglement between the different modes. In the case of global pure states, knowledge of the reduced states …
