Graph MBO on Star Graphs and Regular Trees.: With Corrections to DOI 10.1007/s00032-014-0216-8

The graph Merriman–Bence–Osher scheme produces, starting from an initial node subset, a sequence of node sets obtained by iteratively applying graph diffusion and thresholding to the characteristic (or indicator) function of the node subsets. One result in [14] gives sufficient conditions on the diffusion time to ensure that the set...

Planning Qubit Movements in Fully Connected Star Graphs

Building a working quantum computer brings many challenges to overcome. For quanum processors, promising qubits seem to be NV-centres in diamond. Such processor is divided into processing units (PUs), each comprising an NV-centre with several carbon spin qubits, and they are interconnected with each other by optical links. The qubits within a PU...
