Quantum error correction may delay, but also cause, entanglement sudden death
, 2008 Dissipation may cause two initially entangled qubits to evolve into a separable state in a finite time. This behavior is called entanglement sudden death (ESD). We study to what extent quantum error correction can combat ESD.

Entanglement invariant for the double Jaynes-Cummings model
, 2008 We study entanglement dynamics between four qubits interacting through two isolated Jaynes-Cummings hamiltonians, via the entanglement measure based on the wedge product.

, 2011 Analyses of phenomena exhibiting finite-time decay of quantum entanglement have recently attracted considerable attention. Such decay is often referred to as sudden vanishing (or sudden death) of entanglement, which can be followed by its sudden ...

Dynamics of the entanglement between two oscillators in the same environment [PDF]
, 2008 We provide a complete characterization of the evolution of entanglement between two oscillators coupled to a common environment. For initial Gaussian states we identify three phases with different qualitative long time behavior: There is a phase where ...

, 2012 We demonstrate an exact mapping of a class of models of two interacting qubits in thermal reservoirs to two separate spin-bath problems. Based on this mapping, exact numerical simulations of the qubits dynamics can be performed, beyond the weak system ...

South African Medical Journal, 2010 Air travel by adults with pulmonary disease requires pre-flight medical evaluation and baseline medical examinations to ensure safe travel. We present a case of sudden death on an aeroplane caused by tension pneumothorax, in a patient with known pulmonary disease.

Sudden Death and Left Ventricular Involvement in Arrhythmogenic Cardiomyopathy [PDF]
, 2019 BACKGROUND: Arrhythmogenic cardiomyopathy (ACM) is an inherited heart muscle disorder characterized by myocardial fibrofatty replacement and an increased risk of sudden cardiac death (SCD).

Sudden death of effective entanglement
, 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.

Sudden Cardiac Death in Athletes - What Can be Done? [PDF]
, 2006 Sudden death in athletes is a rare event but brings with it an impact that goes beyond sport. There are many causes of sudden death during exercise.
