dc.description.abstractIn order for quantum key distribution (QKD) to move from the lab to widespread adoption, it will need to be compatible with existing infrastructure. To that end, I demonstrate an implementation of QKD with entangled photons on active, standard telecommunications ber. By using a wavelength outside of the conventional band used by telecommunications tra c, I achieve minimal disruption to either the quantum or classical signals. In an attempt to extend the reach of QKD with entangled photons I studied the parameters of these systems. I developed a model for the number of measured two-fold coincidences that maximizes the secure key rate (SKR), for any combination of system parameters, using a symbolic regression algorithm based on simulated data. I validated this model against experimental data, and demonstrated its usefulness by applying it to simulations of QKD between the ground and a satellite and in optical bers. Finally, I worked on a step towards a new entangled photon source that is a hybrid between visible and telecommunications wavelengths by building a hybrid single photon source.en
