Rotation sensing with a compact Penning trapped calcium ion crystal system*

In traditional mechanics, harmonic oscillators could be utilized for force, acceleration or rotation measurement. The traditional harmonic oscillators usually composed of a mass block. Here we describe a quantum harmonic oscillator based on trapped ion crystal. These penning trapped ions can form a 2D ion crystal. The calcium ions are cooled through lasers and driven by RF electronic magnetic field. The spins of the ions and the harmonic motion are coupled through a laser. Just like the traditional oscillators, we try to figure out if the trapped ions could form a rotation sensor. We also will show the compact penning trap design in our lab. In the penning trap, the super conducting magnet will be replaced by permanent magnet. The cost and the volume of the trap are greatly reduced.
