Dynamics of multi-modes maximum entangled coherent state over amplitude damping channel

TL;DR

This paper investigates how multi-mode maximally entangled coherent states degrade when transmitted through an amplitude damping channel, revealing their fragility and entanglement decay behavior under different noise conditions.

Contribution

It provides a detailed analysis of the entanglement dynamics of multi-mode maximally entangled coherent states in amplitude damping channels, highlighting the effects of transmissivity and mode number.

Findings

Entanglement decays smoothly at higher transmissivity rates.

States are highly fragile at low transmissivity, suffering phase flip errors.

Increasing modes hastens entanglement loss.

Abstract

The dynamics of maximum entangled coherent state travels through an amplitude damping channel is investigated. For small values of the transmissivity rate the travelling state is very fragile to this noise channel, where it suffers from the phase flip error with high probability. The entanglement decays smoothly for larger values of the transmissivity rate and speedily for smaller values of this rate. As the number of modes increases, the travelling state over this noise channel loses its entanglement hastily. The odd and even states vanish at the same value of the field intensity.
