Communication Capacity of W States

Abstract

Tripartite entanglement of three qubits can be classified based on the stochastic local operations and classical communications. Such entanglement are divided into two categories: GHZ states and W states. In this paper, we present the communication capacity of W states of arbitrary n qubits. We firstly evaluate the partition-depended communication capacity of bipartite W states including hyper-entangled W states. And then we compute the concordant communication capacity of W states, which is independent of partitions of W states.
