Effect of quantum information scrambling on bound entangled states

Abstract

Spreading information in physical systems is a common phenomenon. However, when the information is quantum in nature, tracking, describing, and quantifying the information is a challenging task. Quantum information scrambling defines the quantum information propagating chaotically over the physical system. This article describes the effect of quantum information scrambling on bound entangled states. A bound entangled state is a particular type of entangled state that carries noisy entanglement. The distillation of this type of entangled state is very difficult. In recent times, the usefulness of these states has been depicted in different applications. The outcome of this study exhibits that quantum information scrambling develops entanglement in the separable portion of the bound entangled states. Although quantum information scrambling reduces entanglement, the study pointed out that quantum information scrambling plays a significant role in activating the bound entangled states by introducing a certain amount of approximately stable entanglement.
