Strongly Interacting Photons

Abstract: Photons are excellent carriers of the information due to the large bandwidth and speed with which they propagate as well as their weak interaction between themselves and with the transparent environment. Those properties straightforwardly lead to the applications in classical and quantum information science. However, Quantum Information Science and Quantum Sensing would greatly profit from strong coupling of photons to matter and efficient interactions between photons. This became a possibility in a recent decade due to the rapid development in the field of Strongly Interacting Photons (SIP). By engineering hybrid systems with an efficient coupling of photons to matter (e.g. atoms or artificial atoms) interactions on a single photon level are achievable [1]. One of the most promising platforms for this purpose are photons propagating in a cloud of Rydberg atoms at the Electromagnetically induced transparency. Other successful platforms include (a) in the optical domain: ensembles of atoms, single atoms in cavities, nano-photonics, opto-mechanics, graphene and quantum dots, and (b) in microwave domain: cavity QED and superconducting circuits. In my talk, I will give an introduction to the field of Strongly Interacting Photons.
