Dissipative Josephson effect in coupled nanolasers
Samuel Fernández-Lorenzo, Diego Porras
Josephson effects are commonly studied in quantum systems in which dissipation or noise can be neglected or do not play a crucial role. In contrast, here we discuss a setup where d…
Hybrid quantum-classical optimization for financial index tracking
Samuel Fernández-Lorenzo, Diego Porras, Juan José García-Ripoll
Tracking a financial index boils down to replicating its trajectory of returns for a well-defined time span by investing in a weighted subset of the securities included in the benc…
Heisenberg scaling with classical long-range correlations
Samuel Fernández-Lorenzo, Jacob A. Dunningham, Diego Porras
The Heisenberg scaling is typically associated with nonclassicality and entanglement. In this work, however, we discuss how classical long-range correlations between lattice sites…
Quantum sensing close to a dissipative phase transition: symmetry breaking and criticality as metrological resources
Samuel Fernández-Lorenzo, Diego Porras
We study the performance of a single qubit-laser as a quantum sensor to measure the amplitude and phase of a driving field. By using parameter estimation theory we show that certai…
