We model a quantum sensor network using techniques from state discrimination. The interaction between qubit detector and the environment is described by unitary operator, we will assume that at most one does interact. task to determine which or if none do. This involves choosing an initial of detectors measurement. consider global measurements in all are measured simultaneously. find entangled ...

Large-scale sensor networks and the vast data sets they produce worldwide are being utilized and published by a rising number of organizations on an ever-increasing frequency. Examples include the global scale ARGOS network of buoys1, the weather networks of the World Meteorological Organization, the global GPS Zenith Total Delay (ZTD) observation network, etc. Significant amount of efforts (e....

Sensor network users currently face enormous challenges, including programming difficulty and the use of unfamiliar, complex interfaces. To date, most usability research with respect to sensor networks have focused on simplifying programming by offering powerful programming abstractions. Unfortunately, such work does little to encourage ordinary users, such as application scientists, to adopt s...
