Bell's Inequality: More Tests Are Needed

TL;DR

This paper argues that despite recent progress in closing loopholes in Bell's inequality tests, further tests are necessary due to unresolved conceptual issues in current experiments.

Contribution

It highlights the need for additional tests of Bell's inequality, emphasizing conceptual limitations in recent experiments that claim to have closed all loopholes.

Findings

Recent experiments have closed some loopholes but not all.

Current tests have conceptual drawbacks.

Further tests are essential for conclusive results.

Abstract

According to recent reports, the last loopholes in testing Bell's inequality are closed. It is argued that the really important task in this field has not been tackled yet and that the leading experiments claiming to close locality and detection efficiency loopholes, although making a very significant progress, have conceptual drawbacks.
