Affect of Simulated Atmospheric Turbulence on Three Entangled Photons

TL;DR

This paper investigates how simulated atmospheric turbulence impacts the entanglement of three-photon GHZ states, showing entanglement degradation correlates with increased entropy and aligns with theoretical Werner curve predictions.

Contribution

It introduces a scheme to measure the effects of atmospheric turbulence on three-photon entanglement, extending prior two-qubit studies to more complex states.

Findings

Entanglement decreases with increased turbulence

Simulated results match Werner curve predictions

Turbulence causes entropy increase in GHZ states

Abstract

The thorough experimental study for the measure of sustainability of the atmospheric turbulence of the entangled photons for two qubit has been analysed by G. Puentes et al. [Phys. Rev. A 75, 032319 (2007)]. Here in this paper we propose a scheme to measure the effect of entanglement in three entangled photon GHZ state with the help of simulated atmospheric turbulence. We simulate the result of affected entangled GHZ state by introducing turbulence in three entangled photon path alternatively. We observe, by introducing the turbulence in photon path we are loosing the entanglement property, because of the increase in entropy. We compare our result with Werner curve and observe that the simulated result perfectly fit with the theoretical result.
