Quantum repeaters are a well known method to overcome the exponential photon loss scaling that quantum states acquire as they are transmitted over long distances. While repeaters for discrete variable encodings of quantum information have existed for some time, novel approaches for continuous variable encoding quantum repeaters have recently been proposed. In this work, we present a method of utilising a discrete variable repeater protocol to distribute continuous variable states and then utilize this to compare the rates of continuous variable entanglement distribution between first generation continuous and discrete variable repeaters.
