Topological input-output theory for directional amplification
Tomás Ramos, Juan José García-Ripoll, Diego Porras
We present a topological approach to the input-output relations of photonic driven-dissipative lattices acting as directional amplifiers. Our theory relies on a mapping from the op…
Scalable multiphoton generation from cavity-synchronized single-photon sources
Ming Li, Juan José García-Ripoll, Tomás Ramos
We propose an efficient, scalable, and deterministic scheme to generate multiple indistinguishable photons over independent channels, on demand. Our design relies on multiple singl…
Experimental reconstruction of the few-photon nonlinear scattering matrix from a single quantum dot in a nanophotonic waveguide
Hanna Le Jeannic, Tomás Ramos, Signe F. Simonsen +8
Coherent photon-emitter interfaces offer a way to mediate efficient nonlinear photon-photon interactions, much needed for quantum information processing. Here we experimentally stu…
Dynamics of Rydberg excitations and quantum correlations in an atomic array coupled to a photonic crystal waveguide
Yashwant Chougale, Jugal Talukdar, Tomás Ramos +1
We study the dynamics of up to two Rydberg excitations and the correlation growth in a chain of atoms coupled to a photonic crystal waveguide. In this setup, an excitation can hop…
