Strong laser physics, non-classical light states and quantum information science

Abstract

directions, we report on the recent progress in the fully quantized description of intense laser-matter interaction and the methods that have been developed for the generation of non-classical light states and entangled states. Also, we discuss the future directions of non-classical light engineering using strong laser fields, and the potential applications in ultrafast and quantum information science. 4 6 Conclusions 43

Quantum Optics as Applied Quantum Electrodynamics is Back in Town

“…Nevertheless, introducing conditioning measurements on the field after the HHG process leads to the generation of non-classical field states by means of optical Schrödinger cat states with high photon numbers [14,[17][18][19]. This suggests the potential applicability of these methods in modern optical quantum technologies and could provide a new photonic platform for information processing [22,23]. In particular, since quantum information processing often requires entangled or superposition states as a resource, there is a clear need to generate such states.…”
