Dynamics of genuine multipartite entanglement under local non-Markovian dephasing (1411.1210v1)
Published 5 Nov 2014 in quant-ph
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.
