      Quantum Machine Learning 

      Romero García, Cristian (2017-01-10)
      [EN] In a world in which accessible information grows exponentially, the selection of the appropriate information turns out to be an extremely relevant problem. In this context, the idea of Machine Learning (ML), a subfield ...

      Quantum ricochets: surface capture, release and energy loss of fast ions hitting a polar surface at grazing incidence 

      Lucas, A. A.; Sunjic, M.; Benedek, G.; Echenique Landiribar, Pedro Miguel (IOP Publishing, 2014-06-09)
      A diffraction mechanism is proposed for the capture, multiple bouncing and final escape of a fast ion (keV) impinging on the surface of a polarizable material at grazing incidence. Capture and escape are effected by elastic ...

      Quantum Simulation Of The Quantum Rabi Model In A Trapped Ion 

      Lv, Dingshun; An, Shuoming; Liu, Zhenyu; Zhang, Jing-ning; Pedernales, Julen S.; Lamata Manuel, Lucas; Solano Villanueva, Enrique Leónidas; Kim, Kihwan (American Physical Society, 2018-04-30)
      The quantum Rabi model, involving a two-level system and a bosonic field mode, is arguably the simplest and most fundamental model describing quantum light-matter interactions. Historically, due to the restricted parameter ...

      Quantum simulations of relativistic quantum physics in circuit QED 

      Simón Pedernales, Julen Jon; Di Candia, Roberto; Ballester, D.; Solano Villanueva, Enrique Leónidas (IOP Publishing, 2013-06)
      We present a scheme for simulating relativistic quantum physics in circuit quantum electrodynamics. By using three classical microwave drives, we show that a superconducting qubit strongly coupled to a resonator field mode ...

      Quantum Simulator for Transport Phenomena in Fluid Flows 

      Mezzacapo, Antonio; Sanz Ruiz, Mikel; Lamata Manuel, Lucas; Egusquiza Egusquiza, Iñigo Luis; S. Succi; Solano Villanueva, Enrique Leónidas (Nature Publishing Group, 2015-08-17)
      Transport phenomena still stand as one of the most challenging problems in computational physics. By exploiting the analogies between Dirac and lattice Boltzmann equations, we develop a quantum simulator based on ...

      Quantum work statistics, Loschmidt echo and information scrambling 

      Chenu, A.; Egusquiza Egusquiza, Iñigo Luis; Molina-Vilaplana, J.; Del Campo, A. (Nature Publishing, 2018-08-22)
      A universal relation is established between the quantum work probability distribution of an isolated driven quantum system and the Loschmidt echo dynamics of a two-mode squeezed state. When the initial density matrix is ...

      Quantum-Gravitational Effects on Primordial Power Spectra in Slow-Roll Inflationary Models 

      Brizuela Cieza, David; Kramer, Manuel (MDPI, 2018-01-08)
      We review the computation of the power spectra of inflationary gauge-invariant perturbations in the context of canonical quantum gravity for generic slow-roll models. A semiclassical approximation, based on an expansion ...

      Quaternary dichotomous voting rules 

      Laruelle, Annick; Valenciano Llovera, Federico (2010-01)
      In this paper we provide a general model of "quaternary" dichotomous voting rules (QVRs), namely, voting rules for making collective dichotomous decisions (to accept or reject a proposal), based on vote profiles in which ...
