Dynamics of genuine multipartite entanglement under local non-Markovian dephasing
arXiv:1411.1210 · doi:10.1016/j.physleta.2014.05.030
Abstract
We study dynamics of genuine entanglement for quantum states of three and four qubits under non-Markovian dephasing. Using a computable entanglement monotone for multipartite systems, we find that GHZ state is quite resilient state whereas the W state is the most fragile. We compare dynamics of chosen quantum states with dynamics of random pure states and weighted graph states.
