Light interaction and quantum transport in atomic chain chirally coupled to a waveguide

2017 · 2017 11th International Congress on Engineered Materials Platforms for Novel Wave Phenomena (Metamaterials)

In this work we considered light interaction with two-level quantum systems chirally coupled to a single guided mode with account for a spin-locking effect. The chiral coupling allows achieving asymmetric interaction between the two-level systems, …

Subtraction and Addition of Propagating Photons by Two-Level Emitters

2024 · Physical Review Letters

Coherent manipulation of quantum states of light is key to photonic quantum information processing. In this Letter, we show that a passive two-level nonlinearity suffices to implement non-Gaussian quantum operations on propagating field modes. In …
