Polarization in quantum photonic sensing [Invited]

In this review, we address the emerging field of quantum photonic sensing leveraging the polarization degree of freedom.We briefly discuss the main aspects of treating polarization in quantum optics, and provide an overview of the main trends in the development of the field and the strategies to realize quantum-enhanced polarization-based sensing as well as a comprehensive survey of the main advancements in the field.We aim at promoting quantum approaches to the researchers in classical optical polarimetry as well as underscoring the sustainability and resourcefulness of the field for prospective applications and attracting the researchers in quantum optics to this new emerging field.
