Query: Coherent Cancellation of Backaction Noise in optomechanical Force
  Measurements   Optomechanical detectors have reached the standard quantum limit in position
and force sensing where measurement backaction noise starts to be the limiting
factor for the sensitivity. A strategy to circumvent measurement backaction,
and surpass the standard quantum limit, has been suggested by M. Tsang and C.
Caves in Phys. Rev. Lett. 105 123601 (2010). We provide a detailed analysis of
this method and assess its benefits, requirements, and limitations. We conclude
that a proof-of-principle demonstration based on a micro-optomechanical system
is demanding, but possible. However, for parameters relevant to gravitational
wave detectors the requirements for backaction evasion appear to be
prohibitive.
