  The sensitivity of future gravitational wave interferometers is expected to
be limited through-out the detection band by quantum vacuum fluctuations, which
can be reduced by quantum non-demolition methods such as squeezed vacuum
injection. However, optical losses in the readout chainseverely limit the
effectiveness of such schemes. We propose an optomechanical device to be
installedat the output of the detector that mitigates the effect of readout
loss, thus allowing the detector tobetter exploit quantum noise evasion
schemes.
