Abstract

We use a double-well optical lattice as an atom interferometer to load and measure atomic number-squeezed states with N = 1 or 2 and Poissonian states with ⟨N⟩ ≈1 into the lattice ground state.

Probing optical lattice states with double well atom interferometry

Philip R. Johnson

Interference patterns produced by binomially splitting atom states in a double well optical lattice can be used to probe many important properties of this system, including double well tilt (and tilt inhomogeneities), the on-site interaction energy U, atom number distribution across the lattice, vibrational excitation, and lattice state coherence, making atom interferometry a powerful tool to analyze and characterize the structure and states of optical lattice systems, an essential task if they are to realize their potential for quantum information and for a variety of other proposed uses.

Preparing and Probing Atomic Number States with an Atom Interferometer

Jennifer Sebby-Strabley, Benjamin L. Brown, Marco Anderlini +4 more

We describe the controlled loading and measurement of number-squeezed states and Poisson states of atoms in individual sites of a double well optical lattice. These states are input to an atom interferometer that is realized by symmetrically splitting individual lattice sites into double wells, allowing atoms in individual sites to evolve independently. The two paths then interfere, creating a matter-wave double-slit diffraction pattern. The time evolution of the double-slit diffraction pattern is used to measure the number statistics of the input state. The flexibility of our double well lattice provides a means to detect the presence of empty lattice sites, an important and so far unmeasured factor in determining the purity of a Mott state.

Observation of atom-number fluctuations in optical lattices via quantum collapse and revival dynamics

Tianwei Zhou, Kaixiang Yang, Zijie Zhu +9 more

Using the quantum collapse and revival phenomenon of a Bose--Einstein condensate in three-dimensional optical lattices, the atom number statistics on each lattice site are experimentally investigated. We observe an interaction driven time evolution of on-site number fluctuations in a constant lattice potential with the collapse and revival time ratio as the figure of merit. Through a shortcut loading procedure, we prepare a three-dimensional array of coherent states with Poissonian number fluctuations. The following dynamics clearly show the interaction effect on the evolution of the number fluctuations from Poissonian to sub-Poissonian. Our method can be used to create squeezed states, which are important in precision measurement.

We create up to 20 dB spin-squeezed states of atomic ensembles using an optical cavity-based measurement. The prepared states are suitable for atomic sensors that require free space release of the atoms.
