    "abstract": "The degree of entanglement in an open quantum system varies according to how\ninformation in the environment is read. A measure of this contextual\nentanglement is introduced based on quantum trajectory unravelings of the open\nsystem dynamics. It is used to characterize the entanglement in a driven\nquantum system of dimension $2\\times\\infty$ where the entanglement is induced\nby the environmental interaction. A detailed mechanism for the\nenvironment-induced entanglement is given.",
