Measurement and completely decoherence

TL;DR

This paper introduces a quantification method for decoherence in quantum systems by analyzing how dephasing measurements transfer coherence to the environment, providing a new perspective on decoherence measurement.

Contribution

It presents a novel approach to quantify decoherence using quantum coherence resource measures and dephasing measurements.

Findings

Dephasing measurement can transfer all coherence to the environment.

Provides a new quantification method for decoherence.

Enhances understanding of coherence transfer in quantum systems.

Abstract

By virtue of quantum coherence resource measure, we show that the dephasing measurement on a coherence basis can transfer the coherence contained in system into environment totally, which gives a quantification of decoherence.
