Implications of exceptional points for few-photon transport in waveguide quantum electrodynamics

Shanshan Xu, Shanhui Fan

We identify a general connection between the physics of exceptional points in non-Hermitian systems and the few-photon bound states in waveguide quantum electrodynamics (QED) systems. We show that, in waveguide QED systems where the local quantum system exhibits an exceptional point, the tightest-bound few-photon bound state occurs at the exceptional point. We illustrate this connection with an explicit computation on a waveguide QED system in which a waveguide is coupled to a Jaynes-Cummings system. Our result provides a quantum signature of the exceptional point physics and indicates that the physics of exceptional point can be used to understand and control the photon-photon interaction.We identify a general connection between the physics of exceptional points in non-Hermitian systems and the few-photon bound states in waveguide quantum electrodynamics (QED) systems.

Photonic transport in disordered multiqubit non-chiral waveguide QED

Imran M. Mirza, John C. Schotland

We study single photon transport through a one-dimensional waveguide side coupled to a position disordered multiqubit array. Particularly, we show how emitter-waveguide coupling influences the formation of localized photonic states under varying disorder strength.
