Experimental observation of environment-induced sudden death of entanglement

Abstract

We demonstrate, using an all-optical setup, the difference between local and global dynamics of entangled quantum systems coupled to independent environments. Even when the environment-induced decay of each system is asymptotic, quantum entanglement may suddenly disappear.

Environment-Induced Sudden Death of Entanglement

Marcelo Pereira de Almeida, Fernando de Melo, Malena O. Hor-Meyll +4 more

We demonstrate the difference between local, single-particle dynamics and global dynamics of entangled quantum systems coupled to independent environments. Using an all-optical experimental setup, we showed that, even when the environment-induced decay of each system is asymptotic, quantum entanglement may suddenly disappear. This "sudden death" constitutes yet another distinct and counterintuitive trait of entanglement.

Observation of the entanglement sudden death

Marcelo Pereira de Almeida, Fernando de Melo, Malena O. Hor-Meyll +4 more

We demonstrate, using an all-optical setup, the difference between local and global dynamics of entangled quantum systems coupled to independent environments. Even when the decay of each system is asymptotic, quantum entanglement may suddenly disappear. We also demonstrate experimentally that measurements performed in the environment affects the local evolution.

Entanglement and decoherence: global versus local dynamics

Marcelo Pereira de Almeida, Fernando de Melo, Malena O. Hor-Meyll +4 more

We demonstrate, using an all-optical setup based on twin-photons, the difference between local and global dynamics of entangled quantum systems coupled to independent environments. A single experimental realization encompasses several kinds of individual qubit dynamics, including exponential decay and oscillatory exchanges between each qubit and its environment. We verify that entanglement may disappear at a finite time, even when the individual properties of each qubit decay exponentially.

Universality of sudden death of entanglement

F. F. Fanchini, Paulo E. M. F. Mendonça, Reginaldo de Jesus Napolitano

We present a constructive argument to demonstrate the universality of the sudden death of entanglement in the case of two non-interacting qubits, each of which generically coupled to independent Markovian environments at zero temperature. Conditions for the occurrence of the abrupt disappearance of entanglement are determined and, most importantly, rigourously shown to be \emph{almost} always satisfied: Dynamical models for which the sudden death of entanglement does not occur are seen to form a highly idealized zero-measure subset within the set of all possible quantum dynamics.

Entanglement and Decoherence

L. Davidovich

The interaction between entangled multi-particle systems with the environment leads to both local dynamics, associated with single-particle dissipation, diffusion, and decay, and to global dynamics, which may provoke the disappearance of entanglement at a finite time [1-6]. This phenomenon may occur even when single-particle decoherence is asymptotic in time, and constitutes yet another distinct trait of entanglement. It has been recently demonstrated, for two qubits under the action of independent environments, using an all-optical setup [7]. In this talk, some of the peculiarities of the dynamics of two-qubit entangled states undergoing decoherence will be reviewed, new features of the experiment realized at the Federal University of Rio de Janeiro [7] will be described, and the extension of these considerations to multi-particle entangled states will be discussed. Scaling laws for the decay of entanglement and its finite-time extinction in multi-particle systems will be discussed.

Sudden Death of Entanglement in a Two-Qubit System Coupled to a Small Environment

G. L. Deçordi, A. Vidiella-Barranco

We study the entanglement dynamics of two interacting qubits, having only one of them coupled to a small environment (single mode thermal field). We verify the existence of sudden death of entanglement in the system.
