Do Hardy-type proposals test nonlocality of single-particle?

TL;DR

The paper critically examines Hardy-type proposals, arguing they either assume nonlocality or rely on local hidden variables, thus failing to conclusively demonstrate nonlocality of single particles.

Contribution

It clarifies the assumptions behind Hardy-type proposals and shows they cannot definitively test nonlocality without additional assumptions.

Findings

Hardy-type proposals assume nonlocality at detection

They rely on local hidden variables or many-worlds interpretations

Such proposals cannot conclusively prove nonlocality of single particles

Abstract

It is argued that Hardy-type proposals assume either nonlocality at detection, and then beg the question, or "local empty waves" (local hidden variables), and then have to accept "many worlds" and cannot prove nonlocality.
