Simulation of the elementary evolution operator with the motional states of an ion in an anharmonic trap.

Following a recent proposal of L. Wang and D. Babikov [J.

Quantum gates in hyperfine levels of ultracold alkali dimers by revisiting constrained-phase optimal control design.

We simulate the implementation of a 3-qubit quantum Fourier transform gate in the hyperfine levels of ultracold polar alkali dimers in their first two lowest rotational levels. The chosen dimer is (41)K(87)Rb supposed to be trapped in an optical lattice. The hyperfine levels are split by a static magnetic field.

One-dimensional quantum description of the bending vibrations of HCN/CNH for high values of the total angular momentum.

For high values of the quantum number of the total angular momentum J (up to J = 20), quantum mechanical eigenstates (eigenvalues and eigenfunctions) are calculated by the method of Gatti et al. (J. Mol.
