    "abstract": "We calculate the entanglement between a pair of polarization-entangled photon\nbeams as a function of the reference frame, in a fully relativistic framework.\nWe find the transformation law for helicity basis states and show that, while\nit is frequency independent, a Lorentz transformation on a momentum-helicity\neigenstate produces a momentum-dependent phase. This phase leads to changes in\nthe reduced polarization density matrix, such that entanglement is either\ndecreased or increased, depending on the boost direction, the rapidity, and the\nspread of the beam.",
