Peculiar Features of Entangled States with Post-Selection

TL;DR

This paper explores the unique properties of entangled quantum states that are post-selected into non-entangled states, revealing unusual behaviors especially during weak measurements at intermediate times.

Contribution

It introduces the study of entangled states with post-selection into non-entangled states and analyzes their peculiar behaviors during weak measurements.

Findings

Unusual behavior observed in post-selected entangled states.

Weak measurements reveal distinctive intermediate-time phenomena.

Post-selection alters the expected quantum correlations.

Abstract

We consider quantum systems in entangled states post-selected in non-entangled states. Such systems exhibit unusual behavior, in particular when weak measurements are performed at intermediate times.
