ul 2 00 5 Alice falls into a black hole : Entanglement in non-inertial frames

  title={ul 2 00 5 Alice falls into a black hole : Entanglement in non-inertial frames},
  author={Ivette Fuentes-Schuller and Robert B. Mann},
Two observers determine the entanglement between two free bosonic modes by each detecting one of the modes and observing the correlations between their measurements. We show that a state which is maximally entangled in an inertial frame becomes less entangled if the observers are relatively accelerated. This phenomenon, which is a consequence of the Unruh effect, shows that entanglement is an observer-dependent quantity in non-inertial frames. In the high acceleration limit, our results can be… CONTINUE READING
