In this paper, we propose the use of multi-photon quantum cryptography to provide higher data exchange rates and security in quantum networks. We investigate different routing strategies and their effects on key rates, path establishment probabilities, and security. Our simulation varies parameters such as the network size, topology, length of fiber channels, and probability of channel decoherence. Lastly, we also examine the effect of including a trusted nodes in the network and examine the key-rates under different routing strategies.
