It is well known that, during inflation, the conformal invariance of theelectromagnetic action has to be broken in order to produce magnetic fields ofobserved strengths today. Often, to further enhance the strengths of themagnetic fields, parity is also assumed to be violated when the fields arebeing generated. In this work, we examine the evolution of the quantum state ofthe Fourier modes of the non-conformally coupled and parity violatingelectromagnetic field during inflation. We utilize tools such as the Wignerellipse, squeezing parameters and quantum discord to understand the evolutionof the field. We show that the violation of parity leads to an enhancement ofthe squeezing amplitude and the quantum discord (or, equivalently, in thiscontext, the entanglement entropy) associated with a pair of opposite wavevectors for one of the two states of polarization (and a suppression for theother state of polarization), when compared to the case wherein parity isconserved. We highlight the similarities between the evolution of the Fouriermodes of the electromagnetic field when parity is violated during inflation andthe behavior of the modes of a charged, quantum, scalar field in the presenceof a constant electric field in a de Sitter universe. We briefly discuss theimplications of the results we obtain.
