We investigate the irreconcilability issue that raises from translating the
search algorithm from the Continuous-Time Quantum Walk (CTQW) framework to the
Adiabatic Quantum Computing (AQC) framework. One major issue is the constant
energy gap in the translated Hamiltonian throughout the AQC schedule. To
resolve the issue in the initial investigation, we choose only Z operator as
the catalyst Hamiltonian and show that this modification keeps the running time
optimal. Inspired by this irreconcilability issue and our solution, we further
investigate to find the proper timing for releasing the chosen catalyst
Hamiltonian and the suitable coefficient function of the catalyst Hamiltonian
in the AQC schedule to improve the Adiabatic local search.Comment: 9 pages, 8 figure
