Attempts to apply quantum field theory to gravitational fields have been made since its invention in the late 1920s. The formal quantum theory of gravity, which characterises any system as an action function in a canonical Hamiltonian approach, has finally reached a state of completion after more than 20 years. In contrast to the situation with the canonical theory, a covariant treatment was also devised to deal with the physical conditions that need consideration of vacuum processes. In this chapter, we begin with a brief history of the development of quantum gravity theory before looking at the applications of two quantization methods to inspiraling neutron star binary systems. We hypothesised the gravitational Higgs mechanism and calculated the quantum corrections to the Newtonian potential of wide inspiraling neutron star binaries in order to examine the mass creation of gravitons and the accompanying quantum effects on the gravitational potential. We use the canonical technique to study the gravitational quantum effects on the dynamics of gravitational quanta radiated from various systems, as well as the covariant treatment to study the gravitational potential of binaries. The quantum effects are also examined in terms of possible detections and limitations.
