Observing different phases for the dynamics of entanglement in an ion trap

Mostrar todas las versiones(2)

The evolution of the entanglement between two oscillators coupled to a common thermal environment is nontrivial. The long time limit has three qualitatively different behaviors (phases) depending on parameters such as the temperature of the bath. The phases include cases with nonvanishing long-term...
