Abstract: An auction-based distributed method for cooperative multi-target tracking by a plurality of satellites, includes distributed target tracking error and utilization computation as an auction bid across the satellite and uses message-passing to find best bid, handles different tracking requirements via definition of bids and modification of task definition used during the bidding process, and selected a list of auction winners to track the target.

Abstract: A method for node cluster assignment in a graph includes identifying neighboring nodes of a first node in the graph, calculating one or more elements of a graph Laplacian of the graph, the one or more elements of the graph Laplacian corresponding to the first node and the neighboring nodes, initializing a first wavefunction associated with the first node with an initial value, evolving the first wavefunction associated with the first node over time based on the initial value, the one or more elements of the graph Laplacian, and previous states of wavefunctions of the neighboring nodes to generate a time-evolved wavefunction vector, and identifying a cluster assignment of the first node based on the time-evolved wavefunction vector.

Abstract: A method for node cluster assignment in a graph includes initializing a plurality of wavefunctions, each one of the plurality of wavefunctions corresponding to nodes of the graph, constructing a plurality of quantum circuits, each corresponding to a graph Laplacian of the graph, evolving the plurality of wavefunctions at the plurality of quantum circuits, each one of the plurality of wavefunctions being evolved to a different time than other ones of the plurality of wavefunctions, measuring evolved states of the plurality of wavefunctions to generate a time-evolved wavefunction vector, and identifying a cluster assignment of a node of the graph based on the time-evolved wavefunction vector.
