Decimation technique for open quantum systems: a case study with driven-dissipative bosonic chains
Álvaro Gómez-León, Tomás Ramos, Diego Porras +1
The unavoidable coupling of quantum systems to external degrees of freedom leads to dissipative (non-unitary) dynamics, which can be radically different from closed-system scenario…
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…
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…
Correlated Dephasing Noise in Single-photon Scattering
Tomás Ramos, Juan José García-Ripoll
We develop a theoretical framework to describe the scattering of photons against a two-level quantum emitter with arbitrary correlated dephasing noise. This is particularly relevan…
Quantum probe of an on-chip broadband interferometer for quantum microwave photonics
P. Eder, T. Ramos, J. Goetz +11
Quantum microwave photonics aims at generating, routing, and manipulating propagating quantum microwave fields in the spirit of optical photonics. To this end, the strong nonlinear…
Implementation of Chiral Quantum Optics with Rydberg and Trapped-ion Setups
Benoît Vermersch, Tomás Ramos, Philipp Hauke +1
We propose two setups for realizing a chiral quantum network, where two-level systems representing the nodes interact via directional emission into discrete waveguides, as introduc…
