Strong causality from weak via continuous monitoring

TL;DR

This paper demonstrates that continuous, unbiased measurements in quantum systems can induce a strong causal arrow of time, transforming the weak causality principle into an apparent causality direction through ongoing monitoring.

Contribution

It introduces a framework showing how repeated measurements can strengthen causality in quantum systems, revealing an emergent arrow of time.

Findings

Repeated measurements induce an apparent arrow of time.

Continuous monitoring enhances perceived causality.

Weak causality can be strengthened through measurement.

Abstract

Repeated unbiased measurements cause a continual application of the weak causality principle, leading to an apparent arrow of time for continuously-monitored quantum systems.
