    We show that the sensitivity and robustness of a label-free optical imaging technique based on stimulated Raman scattering (SRS) can be enhanced by using resonant optical transitions in a Raman adiabatic passage scheme. ...
  • Flux enhancement of photons entangled in orbital angular momentum 

    Palacios, Silvana; León Montiel, R.D.J.; Hendrych, Martin; Valencia, Alejandra; Pérez Torres, Juan (2011-07-18)
    Article
    Restricted access - publisher's policy
    Entangled photons are generally collected by detection systems that select their certain spatial modes, for example using single-mode optical fibers. We derive simple and easy-to-use expressions that allow us to maximize ...
  • Implementation of a spatial two-dimensional quantum random walk with tunable decoherence 

    Svozilik, Jiri; León Montiel, R.D.J.; Pérez Torres, Juan (2012-11)
    Article
    Open Access
    We put forward a versatile and highly scalable experimental setup for the realization of discrete two-dimensional quantum random walks with a single-qubit coin and tunable degree of decoherence. The proposed scheme makes ...
  • Measurement of the temperature of atomic ensembles via which-way information 

    León Montiel, R.D.J.; Pérez Torres, Juan (2012-03-05)
    Article

    We unveil the relationship existing between the temperature of an ensemble of three-level atoms in a configuration, and the width of the emission cone of Stokes photons that are spontaneously emitted when atoms are ...
