Measurement incompatibility and Channel Steering

TL;DR

This paper explores the relationship between measurement incompatibility and channel steering in quantum theory, establishing a connection that enhances understanding of quantum correlations and their implications.

Contribution

It introduces a link between the lack of joint measurability and channel steering, expanding the theoretical framework of quantum measurement and steering phenomena.

Findings

Incompatible measurements lead to EPR steering.

Channel steering is a generalized form of EPR steering.

A connection between joint measurability and channel steering is established.

Abstract

Incompatible measurements in quantum theory always lead to Einstein-Podolsky-Rosen (EPR)-Schr\"{o}dinger steering. Channel steering which is a generalized notion of EPR-Schr\"{o}dinger steering, has been introduced recently. Here we establish a connection between lack of joint measureability and channel steering.
