We review the current research on precision spectroscopy and quantum optics applications of laser-cooled lanthanides. We discuss the specific electronic structure of hollow atoms, which determine prospects for application in optical frequency standards and in quantum simulators based on spin interactions in optical lattices. Using the example of the thulium atom, we describe the specifics of laser cooling, optical lattice trapping techniques, and clock transition spectroscopy using spectrally narrow lasers.We review the current research on precision spectroscopy and quantum optics applications of laser-cooled lanthanides.

Quantum computing with magnetic atoms in optical lattices of reduced periodicity

Boris Ravaine, Andrei Derevianko, P. R. Berman

We investigate the feasibility of combining Raman optical lattices with a quantum computing architecture based on lattice-confined magnetically interacting neutral atoms. A particular advantage of the standing Raman field lattices comes from reduced interatomic separations leading to increased interatomic interactions and improved multiqubit gate performance. Specifically, we analyze a $J=3∕2$ Zeeman system placed in ${\ensuremath{\sigma}}_{+}\text{\ensuremath{-}}{\ensuremath{\sigma}}_{\ensuremath{-}}$ Raman fields which exhibit $\ensuremath{\lambda}∕4$ periodicity. We find that the resulting controlled-NOT (CNOT) gate operations times are in the order of millisecond. We also investigate motional and magnetic-field induced decoherences specific to the proposed architecture.We investigate the feasibility of combining Raman optical lattices with a quantum computing architecture based on lattice-confined magnetically interacting neutral atoms.

Microwave Atomic Clock in the Optical Lattice with Specific Frequency

Xiaoji Zhou, Xuzong Chen, Jingbiao Chen +2 more

A scheme for a microwave atomic clock is proposed for Cs or Rb atoms trapped in a blue detuned optical lattice. The ac Stark shift of the clock transition due to a trapping laser is calculated. We analyze it at some specific laser wavelength. Compared with the case of the fountain clock, the cavity related shifts, the collision shift and the Doppler effect are eliminated or suppressed dramatically in an atomic lattice clock. By analyzing various sources of clock uncertainty, a microwave atomic lattice clock with a high accuracy and small volume is feasible.A scheme for a microwave atomic clock is proposed for Cs or Rb atoms trapped in a blue detuned optical lattice.
