Kavli Affiliate: Stephanie Wehner | First 5 Authors: Bethany Davies, Bethany Davies, , , | Summary: In the performance analysis of quantum networks, it is common to approximate bipartite entangled states as either being Bell-diagonal or Werner states. We refer to these as twirled approximations because it is possible to bring any state to such […]
