Query: Gravity-wave interferometers as probes of a low-energy effective quantum
  gravity   The interferometry-based experimental tests of quantum properties of
space-time which the author sketched out in a recent short Letter [Nature 398
(1999) 216] are here discussed in self-contained fashion. Besides providing
detailed derivations of the results already announced in the previous Letter,
some new results are also derived; in particular, the analysis is extended to a
larger class of scenarios for space-time fuzziness and an absolute bound on the
measurability of the amplitude of a gravity wave is obtained. It is argued that
these studies could be helpful for the search of a theory describing a first
stage of partial unification of Gravity and Quantum Mechanics.
