“…The two spin components of the ion's wavefunction evolve along different paths in phase space after the first kick, and are then returned to their original position after the second. This is similar to other atomic interferometry experiments [11,12], with trap evolution playing the role of the atomic reflectors.…”

We report entanglement of a single atom's hyperfine spin state with its motional state in a time scale of less than 3 ns. We engineer a short train of intense laser pulses to impart a spin-dependent momentum transfer of AE2@k. Using pairs of momentum kicks, we create an atomic interferometer and demonstrate collapse and revival of spin coherence as the motional wave packet is split and recombined. The revival after a pair of kicks occurs only when the second kick is delayed by an integer multiple of the harmonic trap period, a signature of entanglement and disentanglement of the spin with the motion. Such quantum control opens a new regime of ultrafast entanglement in atomic qubits.

“…In particular, this allows us to investigate a large momentum transfer matter-wave splitter based on high-order Bragg reflection and enables the production of arrays of trapped BECs by multiple splitting using time-dependent partial Bragg mirrors. A related procedure has recently been realized using Kapitza-Dirac scattering, allowing the implementation of atom interferometry by subsequently recombining the split clouds [13].…”

We report on measurements of splitting Bose-Einstein condensates (BEC) by using a time-dependent optical lattice potential. First, we demonstrate the division of a BEC into a set of equally populated components by means of time-dependent control of Landau-Zener tunneling in a vertical lattice potential. Next, we apply time-dependent optical Bragg mirrors to a BEC oscillating in a harmonic trap. We demonstrate high-order Bragg reflection of the condensate due to multiphoton Raman transitions, where the depth of the optical lattice potential allows for a choice of the order of the transition. Finally, a combination of multiple Bragg reflections and Landau-Zener tunneling allows for the generation of macroscopic arrays of condensates with potential applications in atom optics and atom interferometry.
