    • Charging assisted by thermalization 
      Hovhannisyan, Karen V.; Barra, Felipe; Imparato, Alberto (American Physical Society, 2020)
      A system in thermal equilibrium with a bath will generally be in an athermal state, if the system-bath coupling is strong. In some cases, it will be possible to extract work from that athermal state, after disconnecting ...
    • Deterministic Generation of Large Fock States 
      Uria, Manuel; Solano, P.; Hermann Avigliano, Carla (American Physical Society (APS), 2020)
      We present a protocol to deterministically prepare the electromagnetic field in a large photon number state. The field starts in a coherent state and, through resonant interaction with one or few two-level systems, it ...
    • Transmission estimation at the cram´er-rao bound for squeezed states of light in the presence of loss and ... 
      Woodworth, Timothy S.; Chan, Kam Wai Clifford; Hermann Avigliano, Carla; Marino, Alberto M. (American Physical Society, 2020)
      Enhancing the precision of a measurement requires maximizing the information that can be gained about the quantity of interest from probing a system. For optical-based measurements, such an enhancement can be achieved ...
