Measurement Induced Nonlocality Quantified by Hellinger Distance and weak measurements

Abstract
In this article, we propose measurement-induced nonlocality (MIN) quantified by Hellinger distance using von Neumann projective measurement. The proposed MIN is a bonafide measure of nonlocal correlation and is resistant to local ancilla problem. We obtain an analytical expression of the Hellinger distance MIN for general pure and mixed states. In addition to comparing with similar measures, we explore the role of weak measurement in capturing nonlocal correlation.
