Entanglement and teleportation via chaotic system

TL;DR

This paper studies how entanglement and quantum teleportation are affected by chaotic dynamics and random parameters in a cavity system, revealing decay patterns and fidelity sensitivities crucial for quantum communication.

Contribution

It introduces an analysis of entanglement decay and teleportation fidelity in chaotic systems with random parameters, highlighting their impact on quantum information protocols.

Findings

Entanglement decays over time with a rate influenced by the random parameter.

Teleportation fidelity decreases with increasing damping rates.

The effective time window for reliable quantum teleportation depends on the correlation length of the randomness.

Abstract

The dynamics of entangled state interacting with a single cavity mode is investigated in the presence of a random parameter. We have shown that degree of entanglement decays with time and rate of decay is defined by features of random parameter. Quantum teleportation through dissipative channal and teleportation fidelity as a function of damping rates has been studied. The sensitivity of the fidelity with respect to random parameter is discussed. We have evaluated the time interval during which one can perform the quantum teleportation and send the information with reasonable fidelity, for a given values of correlation length of random parameter.
