Abstracts: 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.
