Decoherence-Induced Sudden Death of Entanglement and Bell Nonlocality
Photonics, 2022 Decoherence due to the unwanted interaction between a quantum system and environment leads to the degradation of quantum coherence. In particular, for an entangled state, decoherence makes a loss of entanglement and Bell nonlocality known as entanglement

Science, 2009 A new development in the dynamical behavior of elementary quantum systems is the surprising discovery that correlation between two quantum units of information called qubits can be degraded by environmental noise in a way not seen previously in studies of dissipation.

Entanglement Sudden Death and Sudden Birth in Semiconductor Microcavities [PDF]
International Journal of Theoretical Physics, 2011 We explore the dynamics of the entanglement in a semiconductor cavity QED containing a quantum well. We show the presence of sudden birth and sudden death for some particular sets of the system parameters.

Entanglement sudden death in band gaps [PDF]
European Physical Journal D, 2010 Using the pseudomode method, we evaluate exactly time-dependent entanglement for two independent qubits, each coupled to a non-Markovian structured environment. Our results suggest a possible way to control entanglement sudden death by modifying the qubit-pseudomode detuning and the spectrum of the reservoirs.

Sudden Birth versus Sudden Death of Entanglement in Multipartite Systems [PDF]
Physical Review Letters, 2008 We study the entanglement dynamics of two cavities interacting with independent reservoirs. Expectedly, we observe that, as the cavity entanglement is depleted, it is transferred to the reservoir degrees of freedom. We find that when the cavity entanglement suddenly disappear, the reservoir entanglement suddenly and necessarily appears.

Disentanglement Dynamics in Nonequilibrium Environments [PDF]
Entropy, 2022 We theoretically study the non-Markovian disentanglement dynamics of a two-qubit system coupled to nonequilibrium environments with nonstationary and non-Markovian random telegraph noise statistical properties. The reduced density matrix of the two-qubit
