Photonucelar processes have been understood for decades to be a golden channel for performing tomography of the gluon density and spatial distribution within nucleons and nuclei. The recent observation of entanglement enabled spin interference in the angular distribution of $rho^0 rightarrow pi^+pi^-$ from diffractive photonuclear interactions has opened new avenues for investigating the gluon distributions in heavy nuclei and allowed the precise neutron skin measurement of gold and uranium nuclei at high energy. However, the mechanism enabling this interference effect is still being investigated. In this talk I will summarize the current observations based on experimental results from multiple collaborations. Next, I will discuss the available theoretical models along with the implications for the future studies of gluon tomography in heavy ion collisions. Finally, I will discuss potential explanations for the effects and potential entanglement enabling this novel form of interference.
