Quantum assisted propulsion is emerging as a potential enabling paradigm for future deep space missions, motivated by the fundamental thermodynamic, energetic, and material constraints that limit classical chemical, nuclear, and electric propulsion architectures. This work presents a unified theoretical framework that integrates quantum field effects, non classical plasma dynamics, and the materials physics of refractory high entropy alloys (RHEAs) to explore propulsion concepts operating beyond the assumptions of continuum thermodynamics and classical transport theory. The proposed framework synthesizes quantum vacuum interactions, Casimir mediated momentum exchange, and quantized plasma surface coupling with the extreme thermo mechanical and radiation tolerance characteristics of RHEAs, which are treated as quantum complex, multi component lattice systems. Using a multi physics approach grounded in quantum electrodynamics, Schrödinger based electronic structure considerations, and statistical mechanics of highly disordered alloys, this study examines how quantum scale energy redistribution, suppressed diffusion kinetics, and localized electronic density of states modulation can influence macroscopic force generation, thermal stability, and structural longevity under deep space propulsion conditions. The analysis is further contextualized within advanced aerospace propulsion architectures, highlighting the role of quantum informed material behaviour in mitigating failure mechanisms associated with extreme heat flux, radiation exposure, and long duration operation. Rather than proposing a specific propulsion device, this paper establishes a foundational theoretical framework that connects quantum physical phenomena with propulsion relevant material responses, offering a physics consistent pathway for the development of next generation deep space propulsion systems.
