Abstract

ABSTRACT Position‐momentum entanglement is a versatile high‐dimensional resource in quantum optics. From fundamental tests of reality to applications in quantum technologies, spatial entanglement has experienced significant growth in recent years. In this review, we explore these advances, beginning with the generation of spatial entanglement, followed by various types of measurements for certifying entanglement, and concluding with different quantum‐based applications. We conclude the review with a discussion and outlook of the field.
