 Abstract: We describe a method to generate light-mediated Hamiltonian interactions between distant quantum systems that is directly applicable for interfacing hybrid quantum systems. This method relies on cascading quantum systems in a loop to realize bidirectional interactions. We establish conditions for the effective interaction to be of either Hamiltonian or dissipative character and analyze the resulting dynamics. We find that in the Hamiltonian regime back-action noise of the light field cancels on one or both of the systems, thus enabling strong coherent coupling. The method is relevant for various applications in the fields of optomechanics and atomic ensembles. We specifically discuss its use for sympathetic cooling, hybrid entanglement generation and unconditional squeezing of such systems.
