  We demonstrate the applicability of the EPR entanglement squeezing scheme for
enhancing the shot-noise-limited sensitivity of a detuned dual-recycled
Michelson interferometers. In particular, this scheme is applied to the
GEO\,600 interferometer. The effect of losses throughout the interferometer,
arm length asymmetries, and imperfect separation of the signal and idler beams
are considered.
