Authors: Hita-Perez, Maria; Jauma, Gabriel; Pino, Manuel; Garcia-Ripoll, Juan Jose Journal: PHYSICAL REVIEW APPLIED Publication date: 2022/01/24 DOI: 10.1103/PhysRevApplied.17.014028 Abstract: A flux qubit can interact strongly when it is capacitively coupled to other circuit elements. This interaction can be separated into two parts, one acting on the qubit subspaces and one in which excited states [...]

Authors: Schmidt, M. K.; Esteban, R.; Giedke, G.; Aizpurua, J.; Gonzalez-Tudela, A. Journal: QUANTUM SCIENCE AND TECHNOLOGY Publication date: 2021/06/11 DOI: 10.1088/2058-9565/abe569 Abstract: Frequency-resolved photon correlations have proven to be a useful resource to unveil nonlinearities hidden in standard observables such as the spectrum or the standard (color-blind) photon correlations. In this manuscript, we analyze [...]

Authors: Bartolomei, M; Hernández, M. I.; Campos-Martínez, J.; Hernández-Lamoneda, R.; Giorgi, G. Journal: CARBON Publication date: 2021/02/24 DOI: 10.1016/j.carbon.2021.02.056 Abstract: The impermeability of defect-free graphene to all gases has been recently contested since experimental evidence (see Nature 579, 229–232 (2020)) of hydrogen transmission through a two-dimensional carbon layer has been obtained. By means of density [...]

Dissipative Josephson effect in coupled nanolasers

2021-06-17T13:39:41+02:00Tags: , |

Authors: Fernandez-Lorenzo, Samuel; Porras, Diego Journal: NEW JOURNAL OF PHYSICS Publication date: 2021/03/01 DOI: 10.1088/1367-2630/abe811 Abstract: 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 dissipative interactions do amplify a photonic Josephson current, [...]
