Abstract
In recent years there has been a great deal of focus on a globe-spanning quantum network,
including linked satellites for applications ranging from quantum key distribution to distributed
sensors and clocks. In many of these schemes, relativistic transformations may have deleterious
effects on the purity of the distributed entangled pairs. In this paper, we make a comparison of
several entanglement distribution schemes in the context of special relativity. We consider three
types of entangled photons states: polarization, single photon, and Laguerre-Gauss mode entangled
states. All three types of entangled states suffer relativistic corrections, albeit in different ways.
These relativistic effects become important in the context of applications such as quantum clock
synchronization where high fidelity entanglement distribution are required
