Generation and detection of bound entanglement
Philipp Hyllus, Carolina Moura Alves, Dagmar Bruss, Chiara Macchiavello
Abstract
We propose a method for the experimental generation of two different families of bound entangled states of three qubits. Our method is based on the explicit construction of a quantum network that produces a purification of the desired state. We also suggest a route for the experimental detection of bound entanglement, by employing a witness operator plus a test of the positivity of the partial transposes.
