1. A quantum computational (QC) device that includes a first multi-qubit (MQ) structure and a second MQ structure coupled to the first MQ structure, the first MQ structure being arranged to provide an adiabatic quantum computation by application of an initial Hamiltonian operator, and the second MQ structure being arranged to provide another adiabatic quantum computation by application of another Hamiltonian operator that is spatially different than the initial Hamiltonian operator, wherein a first sub quantum computational circuit corresponds to the first MQ structure, and a second sub quantum computational circuit corresponds to the second MQ structure.
