TL;DR: In this article, a joint experimental and theoretical study on strong field photo-ionization of sodium atoms using chirped femtosecond laser pulses is presented, where different excitation pathways enabling control are identified by simultaneous ionization and measurement of photoelectron angular distributions employing the velocity map imaging technique.

TL;DR: This work proposes an addressing method using composite sequences of laser pulses that dramatically reduces the addressing error in a lattice of closely spaced atoms or ions and at the same time significantly enhances the robustness of qubit manipulations.

TL;DR: In this article, the exact analytical solution of the degenerate Landau-Zener model, wherein two bands of degenerate energies cross in time, was derived by using the Morris-Shore transformation, which reduces the fully coupled system to a set of independent non-degenerate two-state systems.

TL;DR: In this article, the Morris-Shore transformation is used to express the propagator in terms of Morris−Shore basis states and Cayley-Klein parameters, which allows us to connect properties of laser pulses to Hilbert-space motion.
