Programming long-range interactions in analog quantum simulators
Cristian Tabares, Alberto Muñoz de las Heras, Jan T. Schneider +1
Long-range interactions are the source of many equilibrium and out-of-equilibrium quantum many-body phenomena. Analog simulators based on ionic, atomic, superconducting, and molecu…
Deterministic generation of grid states with programmable nonlinear bosonic circuits
Yanis Le Fur, Javier Lalueza-Puértolas, Carlos Sánchez Muñoz +2
Bosonic quantum error correction enables hardware-efficient protection of quantum information by encoding logical qubits in harmonic oscillators. Bosonic grid states, such as Gotte…
Unidirectional lasing in nonlinear Taiji micro-ring resonators
Alberto Muñoz de las Heras, Iacopo Carusotto
We develop a general formalism to study laser operation in active micro-ring resonators supporting two counterpropagating modes. Our formalism is based on the coupled-mode equation…
Theory of quantum spin-Hall topological lasers
Alberto Muñoz de las Heras, Iacopo Carusotto
We theoretically investigate a quantum spin-Hall topological laser formed by an array of dielectric ring resonators endowed of saturable gain. The system preserves time-reversal sy…
Topological, multi-mode amplification induced by non-reciprocal, long-range dissipative couplings
Carlos Vega, Alberto Muñoz de las Heras, Diego Porras +1
Non-reciprocal couplings or drivings are known to induce steady-state, directional, amplification in driven-dissipative bosonic lattices. This amplification phenomenon has been rec…
Directional transport and nonlinear localization of light in a one-dimensional driven-dissipative photonic lattice
Tony Mathew Blessan, Bastián Real, Camille Druelle +11
Photonic lattices facilitate band structure engineering, supporting both localized and extended modes through their geometric design. However, greater control over these modes can…
