7 p, 561.1 KB Filtering of matter-wave vibrational states via spatial adiabatic passage / Loiko, Yury (National Academy of Sciences of Belarus. Institute of Physics) ; Ahufinger, Verònica (Universitat Autònoma de Barcelona. Departament de Física) ; Corbalán, R. (Ramón) (Universitat Autònoma de Barcelona. Departament de Física) ; Birkl, Gerhard (Universität Darmstadt. Institut für Angewandte Physik, Technische) ; Mompart Penina, Jordi (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
We discuss the filtering of the vibrational states of a cold atom in an optical trap by chaining this trap with two empty ones and adiabatically controlling the tunneling. Matter-wave filtering is performed by selectively transferring the population of the highest populated vibrational state to the most distant trap while the population of the rest of the states remains in the initial trap.

8 p, 406.5 KB Quantum-state storage and processing for polarization qubits in an inhomogeneously broadened Λ-type three-level medium / Viscor, Daniel (Universitat Autònoma de Barcelona. Departament de Física) ; Ferraro, Alessandro (Universitat Autònoma de Barcelona. Departament de Física) ; Loiko, Yury (National Academy of Sciences of Belarus. Institute of Physics) ; Mompart Penina, Jordi (Universitat Autònoma de Barcelona. Departament de Física) ; Ahufinger, Verònica (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
We address the propagation of a single-photon pulse with two polarization components, i. e. , a polarization qubit, in an inhomogeneously broadened "phaseonium" Λ-type three-level medium. We combine some of the nontrivial propagation effects characteristic for this kind of coherently prepared systems and the controlled reversible inhomogeneous broadening technique to propose several quantum information-processing applications, such as a protocol for polarization qubit filtering and sieving as well as a tunable polarization beam splitter.
