【 摘 要 】

The objective of this research is to design, fabricate, and demonstrate a microfabricatedmonolithic ion trap for applications in quantum computation and quantum simulation.Most current microfabricated ion trap designs are based on planar-segmented surface electrodes.Although promising scalability to trap arrays containing ten to one hundred ions,these planar designs suffer from the challenges of shallow trap depths, radial asymmetry ofthe confining potential, and electrode charging resulting from laser interactions with dielectricsurfaces. In this research, the design, fabrication, and testing of a monolithicand symmetric two-level ion trap is presented. This ion trap overcomes the challenges ofsurface-electrode ion traps. Numerical electrostatic simulations show that this symmetrictrap produces a deep (1 eV for 171Yb+ ion), radially symmetric RF confinement potential.The trap has an angled through-chip slot that allows back-side ion loading and generousthrough laser access, while avoiding surface-light scattering and dielectric charging thatcan corrupt the design control electrode compensating potentials. The geometry of the trapand its dimensions are optimized for trapping long and linear ion chains with equal spacingfor use with quantum simulation problems and quantum computation architectures.
