Activity Overview:

The research activity is based on our recent breakthrough achievements where the process of high harmonic generation induced by intense laser-matter interactions has been used for the generation of coherent state superpositions (optical Schrodinger "cat" states) and massively entangled light states ranging from the far-IR to extreme-ultraviolet(XUV)  [Nature Phys. 17, 1104 (2021); PRA, 105, 033714 (2022); PRL, 128, 123603 (2022); PRX Quantum 4, 010201 (2023), Rep. Prog. Phys. 86, 094401 (2023), PRL 132, 143603 (2024)].

The activity focuses on the development of new schemes for the generation of a new class of novel non-classical light states that will be used for novel investigations in quantum technology. In particular, it targets on the implementation of quantum operations (e.g. Sci. Rep., 6, 32821 (2016), Nature Comms, 8, 15170 (2017), PRL, 122, 193602 (2019), arXiv:2409.02016) in a variety of intense laser-matter interactions (atoms, molecules, solids) (PRB 109, 035203 (2024), Book in Word Scientific (2024), PRA, 109, 033706 (2024), arXiv:2408.07577) for the generation of controllable high photon number non-classical (e.g. optical "cat" and squeezed light states) of “massively” entangled coherent light state superpositions, for applications in quantum technologies, including non-linear quantum optics (arXiv:2306.14480), quantum metrology/sensing, quantum communication and quantum information processing.
