Distance and Coupling Dependence of Entanglement in the Presence of a Quantum Field

12 May 2015 Hsiang Jen-Tsung Hu B. L.

We study the entanglement between two coupled detectors, whose internal degrees of freedom are modeled by harmonic oscillators, interacting with a common quantum field, paying special attention to two less studied yet important features: finite separation and direct coupling. Distance dependence is essential in quantum teleportation and relativistic quantum information considerations... (read more)
