Experimental Quantum Electrodynamics

Traditional approaches to quantum optics are rooted in the reciprocal, frequency-momentum space. In this talk, I will discuss recent advances toward sub-cycle quantum optics, where, instead, quantum fields are accessed in a localized region of space-time [1-2]. Both regimes will be compared side-by-side to contrast the advantages of each approach, with a particular emphasis on quantum sensing proposals [3-5] in the mid-infrared frequency range.
In the concluding part of the talk, I will summarize recent advances in producing few-cycle bright one- and two-mode squeezed vacuum states in a single few-cycle spatio-temporal mode with macroscopic photon occupation [6]. Such capabilities are poised to unlock a new era of (extreme) nonlinear quantum optics in the attosecond regime [7].
