    "abstract": "Entanglement between particle and detector is known to be inherent in the\nmeasurement process. Gurvitz recently analyzed the coupling of an electron in a\ndouble dot (DD) to a quantum point contact (QPC) detector. In this paper we\nexamine the dynamics of entanglement that result between the DD and QPC. The\nrate of entanglement is optimized as a function of coupling when the electron\nis initially in one of the dots. It decreases asymptotically towards zero with\nincreased coupling. The opposite behavior is observed when the DD is initially\nin a superposition: the rate of entanglement increases unboundedly as the\ncoupling is increased. The possibility that there are conditions for which\nmeasurement occurs versus entanglement is considered.",
