Non-classical and entangled light states are of fundamental interest in quantum mechanics and they are a powerful tool for the emergence of new quantum technologies. The development of methods that can lead to the generation of such light states is t

Quantum state engineering of light is of great interest for quantum technologies, particularly generating non-classical states of light, and is often studied through quantum conditioning approaches. Recently, we demonstrated that such approaches can

Squeezing of optical fields, used as a powerful resource for many applications, and the radiation properties in the process of high harmonic generation have thus far been considered separately. In this Letter, we want to clarify that the joint quantu

Optical Schr\"odinger "cat" states created by superpositions of coherent light states, correspond to an optical analog of the Schr\"odinger's cat in his $\textit{Gedankenexperiment}$. These non-classical light states are generated by means of quantum
