Sudden Death of Entanglement: Classical Noise Effects [PDF]
Optics Communications, 2006 When a composite quantum state interacts with its surroundings, both quantum coherence of individual particles and quantum entanglement will decay. We have shown that under vacuum noise, i.e., during spontaneous emission, two-qubit entanglement may ...

Entanglement breaking channels and entanglement sudden death [PDF]
Physical Review A, 2016 The occurrence of entanglement sudden death in the evolution of a bipartite system depends on both the initial state and the channel responsible for the evolution.

The Geometry of Entanglement Sudden Death [PDF]
New 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 effective entanglement [PDF]
Physical 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.

Entanglement Sudden Death in Band Gaps [PDF]
The European Physical Journal D, 2009 Using the pseudomode method, we evaluate exactly time-dependent entanglement for two independent qubits, each coupled to a non-Markovian structured environment.

Entanglement sudden death and sudden birth in two uncoupled spins [PDF]
Physica Scripta, 2009 We investigate the entanglement evolution of two qubits interacting with a common environment trough an Heisenberg XX mechanism. We reveal the possibility of realizing the phenomenon of entanglement sudden death as well as the entanglement sudden birth ...

Entanglement sudden death in qubit-qutrit systems [PDF]
Physics Letters A, 2007 We demonstrate the existence of entanglement sudden death (ESD), the complete loss of entanglement in finite time, in qubit-qutrit systems. In particular, ESD is shown to occur in such systems initially prepared in a one-parameter class of entangled ...

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