Quantum Enhanced Classical Sensor Networks
The quantum enhanced classical sensor network consists of clusters of
entangled quantum states that have been trialled times, each feeding
into a classical estimation process. Previous literature has shown that each
cluster can {ideally} achieve an estimation variance of for
sufficient . We begin by deriving the optimal values for the minimum mean
squared error of this quantum enhanced classical system. We then show that if
noise is \emph{absent} in the classical estimation process, the mean estimation
error will decay like . However, when noise is
\emph{present} we find that the mean estimation error will decay like
, so that \emph{all} the sensing gains obtained from the
individual quantum clusters will be lost
