    • Classical and quantum-mechanical scaling of ionization from excited hydrogen atoms in single-cycle THz pulses 

      Chovancova, Michaela; Aguen, H.; Rørstad, J. J.; Hansen, J. P. (Peer reviewed; Journal article, 2017-08-25)
      Excited atoms, or nanotip surfaces, exposed to strong single-cycle terahertz radiation emit electrons with energies strongly dependent on the characteristics of the initial state. Here we consider scaling properties of the ...

    • Optimal preparation of graph states 

      Cabello, Adán; Danielsen, Lars Eirik; López-Tarrida, Antonio J.; Portillo, José R. (Peer reviewed; Journal article, 2011-04-12)
      We show how to prepare any graph state of up to 12 qubits with: (a) the minimum number of controlled-Z gates, and (b) the minimum preparation depth. We assume only one-qubit and controlled-Z gates. The method exploits the ...
