Contribution

It provides a detailed analysis of entanglement dynamics, showing how free, bound, and separable states can transition under thermal decoherence.

Findings

Free entangled states can become bound or separable in finite time

Bound or separable states can become distillable entangled states

Finite temperature decoherence causes complex entanglement transitions

Abstract

Distillability sudden death and sudden birth in a two-qutrit system under decoherence of finite temperature is studied in detail. By using of the negativity and realignment criterion, it is shown that certain initial prepared free entangled states may become bound entangled or separable states in a finite time. Moreover, initial prepared bound entangled or separable states also may become distillabile entangled states in a finite time.
