Highly transparent nanostructured metasurfaces are emerging as an important class of modern photonic elements. The metasurfaces can open a pathway for ultra-compact quantum-optics devices. This seminar will present the latest theoretical and experimental developments on the creation of quantum-entangled photons through the process of spontaneous nonlinear wave mixing in metasurfaces.

We then discuss the possibility for arbitrary transformation of quantum entanglement for two-photon quantum states. We will also present the results on the measurement of quantum states, including a scalable tomography implementation, quantum state discrimination, monitoring deviations from a target state, and detecting errors in transmission.

Finally, we will discuss a ghost imaging protocol with metasurfaces, allowing for discrimination of polarisation objects and simultaneous detection of their orientation. Such metasurface-enabled functionalities can contribute to a variety of practical applications including quantum communications, imaging, and metrology.
