W-like states are not Necessary for Totally Correct Quantum Anonymous Leader Election

Quantum Physics 2014-06-04 v1

Abstract

I show that W-like entangled quantum states are not a necessary quantum resource for totally correct anonymous leader election protocols. This is proven by defining a symmetric quantum state that is n-partite SLOCC inequivalent to the W state, and then constructing a totally correct anonymous leader election protocol using this state. This result, which contradicts the previous necessity result of D'Hondt and Panangaden, furthers our understanding of how non-local quantum states can be used as a resource for distributed computation.
