EPR entanglement & quarter wave plate

[RandallB]

Does anyone know of a reference that describes the effect of adding a quarter wave plate or even a half wave plate placed at 0⁰ / 90 ⁰ and 45⁰ positions in just one leg of a EPR entanglement polarization experiment. This would be in addition to the half wave plate in each leg already in place to set the polarization angles of the detectors.

Something from an experimenter detailing correlation results of a real experiment.
Or from a theoretician predicting (and maybe explaining) what the results would be if the experiment were run.

I'm sorry, but I am not aware of any references that specifically address this topic. However, there are a number of articles that discuss the use of quarter-wave plates and half-wave plates in polarization entanglement experiments. For example, "Quarter-Wave Plate Entangled Photon Pair Source" by Takashi Yamamoto et al. (https://arxiv.org/abs/1901.08574) discusses the use of a quarter-wave plate to generate polarization-entangled photon pairs. Additionally, "Quantum State Engineering of Polarization-Entangled Photon Pairs Generated from Spontaneous Parametric Down-Conversion with Half-Wave Plates" by Xing-You Wang et al. (https://www.osapublishing.org/oe/abstract.cfm?uri=oe-20-17-19621) discusses the use of half-wave plates to generate polarization-entangled photon pairs. These papers may provide more insight into the effect of adding a quarter-wave or half-wave plate in one leg of an EPR entanglement polarization experiment.
