| Abstract: | Ability for the on-demand generation and manipulation of non-classical states of light is a cornerstone of scalable quantum information processing. In my talk, I will describe how emerging field of waveguide quantum electrodynamics (WQED), studying interaction of photons propagating in a waveguide with localized quantum emitters, paves new routes towards flexible control over the photon-photon correlations. Specifically, I will consider emergence of photonic entanglement in a waveguide-coupled array of two level systems with modulated resonance frequencies. It will be shown how modulation may impose symmetry constraints on multi-photon emission leading to the symmetry-protected quantum correlations. Furthermore, I will describe a protocol for deterministic generation of designed multi-photon entangled states in the modulated arrays of two-level systems. |
