The geometry of entanglement sudden death
Marcelo O Terra Cunha
Show affiliationsIn 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. A classification of possible scenarios is presented, with important known examples classified. Suggestions of theoretical and experimental examples are given and large dimensional and multipartite versions of the effect are briefly discussed.
