Title: Mapping graph
coloring to quantum annealing
Abstract:
Adiabatic quantum computation (AQC) is an alternative to the
gate model quantum computation and operates in a working graph
such as the Chimera of the DWave Systems. These physical systems
are suitable for quantum annealing (QA) which is a metaheuristic
capable to find a global minimum of a given objective function
from a set of candidate solutions. As such, problems like graph
coloring can be mapped to quantum hardware resorting, for example,
to pseudoBoolean constraints. The SATyrus approach allows us to
convert the constraints to an energy minimization problem which
can be translated to a quadratic unconstrained binary optimization
(QUBO) problem by applying polynomial reduction, a proper
formulation for the DWave machine. The problem was implemented
using three different approaches: (1) classical, QUBO using
simulated annealing (SA) in a von neumann machine, (2) quantum 1,
QUBO using the DWave quantum machine and reducing polynomial
degree using a DWave library, and (3) quantum 2, QUBO using the
DWave quantum machine and reducing polynomial degree using our
own implementation. We conclude that (a) the variation of penalty
terms did not have a significant impact in the number of solutions
found, (b) QA produce better heuristics for this specific problem
than SA since we consistently obtained always more solutions with
the QA approach.

Title: Early fault
detection and mitigation in complex systems
Abstract:
Complex systems experience numerous faults daily, many of these faults are none systems impacting. However, some faults are system impacting and some faults experience a propagation beyond a given system and effect the entire complex system. Understanding these failures and attempting to predict through mitigation factors can greatly enhance total system stability. Through this work I walk through system fault analysis and propose a few mitigation techniques for reducing impact of complete system effecting faults.
