We will discuss new sampling algorithms that are hard for classical computers but can be solved with linear optical quantum processors and techniques for implementing universal quantum gates using strong optical non-linearities and Gaussian optics.
Cavity optomechanics allows the first direct observation of superfluid thermodynamical motion. Laser cooling and strong quartic nonlinearities are both observed, enabling prospective applications in quantum engineering, precision sensing, and studies of emergent quantum phenomena.
We develop a three-dimensional (3D) monolithic ion trap that has advantages of both 3D geometry trap and surface trap.

The hybrid ion trap will be used for quantum information experiment.
