Grover's quantum search and its generalization, quantum amplitude amplification, provide a quadratic advantage over classical algorithms for a diverse set of tasks but are tricky to use without knowing beforehand what fraction λ of the initial state is comprised of the target states. In contrast, fixed-point search algorithms need only a reliable lower(More)
Performing exact inference on Bayesian networks is known to be #P-hard. Typically approximate inference techniques are used instead to sample from the distribution on query variables given the values e of evidence variables. Classically, a single unbiased sample is obtained from a Bayesian network on n variables with at most m parents per node in time O(nmP(More)

Mobile phones with capabilities such as media capture and location detection have become popular among consumers, and this has made possible the development of location-based mobile annotation sharing applications. The present research investigates the creation of mobile annotations from three perspectives: the recipients of the annotations, the type of(More)
