We investigate several aspects of realizing quantum computation using entangled polar molecules. We discuss methods for realizing quantum computation in the gate model, the measurement-based model and the adiabatic model using polar molecules. Moreover, we explore the possibility of a novel quantum computing model built with coupled 2-level systems. The quantum coherent states formed by coupled 2-level systems have unique properties that have inspired numerous ideas in excitonic systems and spin systems. In this study we derive a well-defined selection rule for these quantum coherent states that allows precise optical control over transitions between multi-excitation manifolds. In addition, we show that the hardcore boson statistics of the excitations leads to an accidental degeneracy among eigenstates that enables population transfer between eigenstates for which direct transition is forbidden. These findings allow us to explore the possibility of manipulating the Fock space of a structure of coupled 2-level systems for the purpose of quantum computing. <br/>
