Sudden birth versus sudden death of entanglement in multipartite systems. [PDF]

open access: yesPhysical Review Letters, 2008
We study the entanglement dynamics of two cavities interacting with independent reservoirs. Expectedly, as the cavity entanglement is depleted, it is transferred to the reservoir degrees of freedom. We find also that when the cavity entanglement suddenly

The Geometry of Entanglement Sudden Death [PDF]

open access: yesNew Journal of Physics, 2007
In open quantum systems, entanglement can vanish faster than coherence. This phenomenon is usually called sudden death of entanglement. In this paper sudden death of entanglement is discussed from a geometrical point of view, in the context of two qubits.

Sudden death of entanglement induced by polarization mode dispersion. [PDF]

open access: yesPhysical Review Letters, 2011
We study the decoherence of polarization-entangled photon pairs subject to the effects of polarization mode dispersion, the chief polarization decoherence mechanism in optical fibers. We show that fiber propagation reveals an intriguing interplay between

Delayed sudden death of entanglement at exceptional points [PDF]

open access: yesPhysical Review A, 2019
Almost a decade ago, physicists encountered a strange quantum phenomenon that predicts an unusual death of entanglement, under the influence of a local noisy environment, known as entanglement sudden death (ESD).

Sudden death of entanglement of two Jaynes–Cummings atoms [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2006
We investigate entanglement dynamics of two isolated atoms, each in its own Jaynes–Cummings cavity. We show analytically that initial entanglement has an interesting subsequent time evolution, including the so-called sudden death effect.

Sudden death of effective entanglement [PDF]

open access: yesPhysical Review A - Atomic, Molecular, and Optical Physics, 2010
Sudden death of entanglement is a well-known effect resulting from the finite volume of separable states. We study the case when the observer has a limited measurement capability and analyse the effective entanglement, i.e.

Time-invariant entanglement and sudden death of nonlocality [PDF]

open access: yesPhysical Review A, 2016
We investigate both theoretically and experimentally the dynamics of entanglement and non-locality for two qubits immersed in a global pure dephasing environment.

Sudden death and sudden birth of entanglement in common structured reservoirs [PDF]

open access: yesPhysical Review A, 2008
We study the exact entanglement dynamics of two qubits in a common structured reservoir. We demonstrate that, for certain classes of entangled states, entanglement sudden death occurs, while for certain initially factorized states, entanglement sudden ...

Sudden death of entanglement at finite temperature [PDF]

open access: yesPhysical Review A, 2007
In this paper we consider the decay of quantum entanglement, quantified by the concurrence, of a pair of two-level systems each of which is interacting with a reservoir at finite temperature T.

Effectiveness of depolarizing noise in causing sudden death of entanglement [PDF]

open access: yesQuantum Information Processing, 2013
Continuing on the recent observation that sudden death of entanglement can occur even when a single qubit of a 2-qubit state is exposed to noisy environment (Yashodamma and Sudha in Results Phys 3:41–45, 2013), we examine the local action of a noise on ...
