Passive photonic CZ gate with two-level emitters in chiral multi-mode waveguide QED
Tomás Levy-Yeyati, Carlos Vega, Tomás Ramos +1
Engineering deterministic photonic gates with simple resources is one of the long-standing challenges in photonic quantum computing. Here, we design a passive conditional gate betw…
Waveguide QED with Quadratic Light-Matter Interactions
Uesli Alushi, Tomás Ramos, Juan José García-Ripoll +2
Quadratic light-matter interactions are nonlinear couplings such that quantum emitters interact with photonic or phononic modes exclusively via the exchange of excitation pairs. Im…
Topological Josephson parametric amplifier array: A proposal for directional, broadband, and low-noise amplification
Tomás Ramos, Álvaro Gómez-León, Juan José García-Ripoll +2
Low-noise microwave amplifiers are crucial for detecting weak signals in fields such as quantum technology and radio astronomy. However, designing an ideal amplifier is challenging…
Driven-dissipative topological phases in parametric resonator arrays
Álvaro Gómez-León, Tomás Ramos, Alejandro González-Tudela +1
We study the phenomena of topological amplification in arrays of parametric oscillators. We find two phases of topological amplification, both with directional transport and expone…
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…
Dynamical photon-photon interaction mediated by a quantum emitter
Hanna Le Jeannic, Alexey Tiranov, Jacques Carolan +11
Single photons constitute a main platform in quantum science and technology: they carry quantum information over extended distances in the future quantum internet and can be manipu…
