DESCRIPTION:&nbsp\;\nThe dawn of the last century marked the onset of the f
 irst quantum revolution\, a period characterized by groundbreaking discove
 ries culminating in the establishment of quantum mechanics. Over time\, th
 e abstract concepts introduced by this new branch of Physics\, evolved int
 o indispensable practical devices shaping our daily lives. This technologi
 cal evolution spurred our actual era\, centered around information exchang
 e and acquisition\, laying the foundation for what is now termed the secon
 d quantum revolution. This phase aims to leverage quantum information scie
 nce\, which harnesses quantum mechanics' properties to propel advancements
  in information processing\, communication\, and computation\, leading to 
 revolutionary quantum technologies.\nAt the heart of advancing quantum tec
 hnologies lies the exploration of what are known as non-classical states -
 -physical manifestations exhibiting behaviors diverging from classical phy
 sics\, necessitating the framework of quantum mechanics for explanation. M
 anipulating and generating these states delineates the frontier of progres
 s in quantum technology. Therefore\, it is crucial to devise methodologies
  for generating and controlling non-classical states. Photonics emerges as
  a promising platform within this context due to its robustness and except
 ional manageability of this kind of states.\nFor the above reasons\, this 
 Thesis adopts a dual focus. Firstly\, we delve into the generation of non-
 classical states of light through strong-field processes. These processes 
 entail interactions between light and matter\, where light intensities con
 tend with the binding forces that keep electrons bound to their respective
  nuclei. Our exploration demonstrates the utility of strong-field phenomen
 a in generating non-classical states of light\, exhibiting intriguing feat
 ures dependent on specific process dynamics and the materials involved in 
 excitation. Secondly\, we investigate the constraints and prerequisites of
  non-classical states of light sources --beyond those derived from the afo
 rementioned strong-field processes-- for the advancement of quantum commun
 ication. In particular\, we analyze quantum key distribution\, aiming to c
 reate a secret key exclusively known by the communicating parties for encr
 ypting and decrypting messages.\nTherefore\, this Thesis can be understood
  as a zeroth step towards leveraging strong-field physics as a prospective
  tool for quantum information science applications\, as well as an explora
 tion about the advances and limitations of photonic-based setups for quant
 um key distribution.\n&nbsp\;\nFriday May 24\, 10:00 h. ICFO Auditorium an
