Description: Author(s): Qi Zhao, Xiao Yuan, and Xiongfeng Ma Witnessing entanglement is crucial in quantum information processing. With properly preparing ancillary states, it has been shown previously that genuine entanglement can be witnessed without trusting measurement devices. In this work we generalize the scenario and show that generic multipartite ent… [Phys. Rev. A 94, 012343] Published Tue Jul 26, 2016

Sometimes the structure of the graph causes the walker to get trapped, such that the probability of finding the marked vertex is limited. We give an example with two linked cliques,… [Phys. Rev.
