Transport Enabled Gates with Integrated Photonics on a Surface Electrode Ion Trap

Many schemes for operating a trapped-ion quantum computer rely on shuttling ions so they can be entangled with their neighbors. To reduce the need for optical modulators and enhance extensibility, it would be advantageous to perform gate operations while the ion is being shuttled using "transport enabled gates” [1]. Using integrated photonics also allows for enhanced extensibility through individual addressing with on-device waveguides. We present results demonstrating transport enabled gate operations on Calcium-40 using light from integrated waveguides on a Sandia fabricated surface-electrode Paul trap. Furthermore, we compare these results to ones obtained using free space beams.
