“…Such schemes have recently been developed by means of intense laser-matter interactions. Specifically, recent theoretical and experimental investigations [52,53,98], conducted using fully quantized approaches in the strong-field limit, have shown that the intense laser-atom interactions and conditioning approaches [99][100][101][102] in the process of high-harmonic generation, can be used for the generation of high photon number non-classical and entangled light states with controllable quantum features [53,98,[103][104][105]. This matter will be further discussed in Sec.…”

“…The drawback of this scheme is that some fraction of the optical field needs to be detected, and is thus inevitably interacting with additional optical devices leading to decoherence and amplitude reduction. Nonetheless, this scheme is very powerful to generate non-classical optical cat states with high photon numbers [16][17][18][19].…”

“…However, recent advances in the quantum optical analysis of HHG has established a new direction in the investigation of strong field physics. This allows to study the quantum mechanical properties of the harmonic radiation, or to take into account the backaction on the driving field [10][11][12][13][14][15][16][17][18][19][20]. In particular, it was shown that conditioning procedures on processes induced by intense laser-matter interaction can lead to the generation of high-photon number controllable non-classical field states in a broad spectral range [16][17][18][19].…”

Quantum information science and intense laser matter interaction are two apparently unrelated fields. However, the recent developments of the quantum optical description of the intense laser driven process of high harmonic generation allow to conceive new light engineering protocols. Here, we introduce the notion of quantum information theory to intense laser driven processes by providing the quantum mechanical description of measurement protocols for high harmonic generation in atoms. We explicitly evaluate conditioning experiments on individual optical field modes, and provide the corresponding quantum operation for coherent states. The associated positive operatorvalued measures are obtained, and give rise to the quantum theory of measurement for the generation of high dimensional entangled states, and coherent state superposition with controllable non-classical features on the attosecond timescale.

Strong--laser--field physics is a research direction that relies on the use of high-power lasers and has led to fascinating achievements ranging from relativistic particle acceleration to attosecond science. On the other hand, quantum optics has been built on the use of low photon number sources and has opened the way for groundbreaking discoveries in quantum technology, advancing investigations ranging from fundamental tests of quantum theory to quantum information processing. Despite the tremendous progress, until recently these directions have remained disconnected. This is because, the majority of the interactions in the strong-field limit have been successfully described by semi-classical approximations treating the electromagnetic field classically, as there was no need to include the quantum properties of the field to explain the observations. The link between strong--laser--field physics, quantum optics, and quantum information science has been developed in the recent past. Studies based on fully quantized and conditioning approaches have shown that intense laser--matter interactions can be used for the generation of controllable entangled and non-classical light states. These achievements open the way for a vast number of investigations stemming from the symbiosis of strong--laser--field physics, quantum optics, and quantum information science. Here, after an introduction to the fundamentals of these research 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.
