Query: Implementation of a Distributed Coherent Quantum Observer   This paper considers the problem of implementing a previously proposed
distributed direct coupling quantum observer for a closed linear quantum
system. By modifying the form of the previously proposed observer, the paper
proposes a possible experimental implementation of the observer plant system
using a non-degenerate parametric amplifier and a chain of optical cavities
which are coupled together via optical interconnections. It is shown that the
distributed observer converges to a consensus in a time averaged sense in which
an output of each element of the observer estimates the specified output of the
quantum plant.
