Abstract

The 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 the emerging field of waveguide quantum electrodynamics (WQED), studying the interaction of photons propagating in a waveguide with localized quantum emitters, paves new routes towards flexible control over the photon-photon correlations. In the first, introductory part of the talk, I will describe the entangled photon states and how they can be used for quantum information processing. I will then discuss how the distinctive features of WQED systems such as photon-mediated long-range interactions between two-level systems facilitate the emergence of strong photon-photon correlations. I will continue by reviewing the state-of-the-art experiments, and in the final part of my talk, I will give a brief overview of my recent results in this field. Specifically, I will describe the protocol of the deterministic generation of multi-photon entangled states in the modulated arrays of two-level systems coupled to the common optical bus.
