“…This ultimately leads to the question whether processes driven by sufficiently large photon number states |n , which have a completely random phase due to the well-defined photon number, allow for the generation of high-order harmonics. Or, even more general, if incoherent radiation can be used to drive the parametric process of HHG as recently observed for spontaneous parametric down-conversion in [29].…”

In the theoretical approaches of the Warsaw School, quantum field theory was always present, and quantum optics was considered to be applied quantum electrodynamics. All of us who grew up in this fantastic community have carried and are still carrying the gospel to others. In particular, now quantum electrodynamics began her run on the red carpet of super intense laser-matter interactions, attosecond physics, and ultrafast laser physics in general. We will elaborate on the recent progress in this direction and on the open questions for future investigations. This paper celebrates the 90th birthday of Professor Iwo Białynicki-Birula, our quantum electrodynamics guru! topics: quantum electrodynamics, strong field physics, quantum state engineering, attoscience

In quantum information processing and high-resolution measurements, a variety of non-classical effects based on entangled photon pairs is used. Non-local Dispersion Cancellation (NDC) is one of these properties, in which the second photon (idler) can be manipulated to cancel the effects of dispersion on the first photon (signal). In this work, non-local dispersion cancellation by using modes of excitation in a Bragg grating slab waveguide is analyzed in detail. We present a complete theoretical analysis of Non-local Dispersion Cancellation (NDC) for frequency-limited entangled photon pairs. For the analysis of the effect of dispersion cancellation, we use a spontaneous parametric down-conversion (SPDC) photon pair source with frequency correlation and anti-correlation as the entangled source. To evaluate the dispersion cancellation effect for information processing applications, the second correlation function is used and calculated as a practical measure. Considering different cases for Bragg Grating waveguide the results on both photons are extracted and discussed. Moreover, we will show that the physical parameters of the waveguide that the second photon is propagated inside will be effective in minimizing the width of the temporal correlation function. Therefore, in this work, we show that by optimizing the Bragg Grating waveguide optical and geometrical parameters, the Non-local Dispersion Cancellation can be done that is used in quantum information processing and high-resolution sensing.
