Temporal imaging is a technique that enables manipulation of temporal optical signals in a manner similar to manipulation of optical images in spatial domain. The main building block of temporal imaging, the time lens, is based on nonlinear optical processes such as the sum- frequency generation or the four-wave mixing. While classical temporal imaging is nowadays a well-established domain, its quantum counterpart is still in its nascent period. In this talk we shall give and overview of the quantum temporal imaging and its application for manipulation of non-classical states of the light.

We explore the use of nonlinear optical methods for important applications in quantum information science. One example is the use nonlinear optical methods in the context of “quantum imaging.” We describe some of the conceptual possibilities afforded by the marriage of quantum and classical imaging methods, and we describe recent work that illustrates some of these features. We also address the complementary issue of how advanced imaging protocols can allow one to utilize and manipulate the enormous information content residing in the transvers structure of a quantum light field.

Nonlinear optical metasurfaces, which relax the phase-matching constraints of bulk nonlinear crystals and allow for precise engineering, are opening new possibilities in the field of quantum photonics. Recent advancements have experimentally demonstrated high-resolution 2D imaging using a 1D detector array by combining quantum ghost imaging and all-optical scanning with spatially entangled photon pairs generated from a nonlinear metasurface. These findings establish metasurfaces as a promising platform for quantum imaging, communications, and sensing applications.
