• Abstract: In quantum information, quantum correlations--particularly entanglement, EPR steering, and quantum discord--stand as interesting resources, powering breakthroughs from secure communication and quantum teleportation to efficient quantum computation. Here, we unveil a theoretical framework for generating and controlling these vital quantum phenomena within a double-cavity molecular optomechanical (McOM) system. This innovative approach leverages strong interactions between confined optical fields and collective molecular vibrations, creating a versatile environment for exploring robust quantum correlations. Our findings reveal that judiciously optimizing the coupling strength between the cavity field and the molecular collective mode leads to a remarkable enhancement of entanglement, quantum steering, and quantum discord. We demonstrate that cavity-cavity quantum correlations can be effectively mediated by the molecular collective mode, enabling a unique pathway for inter-cavity quantum connectivity. Moreover, the quantum entanglement generated in our McOM system exhibits robustness against thermal noise, persisting at temperatures approaching 1000 K. This strong resilience, qualifies molecular optomechanics as a compelling architecture for scalable, room-temperature quantum information processing and the practical realization of quantum networks.
