| description | We report the design, fabrication, and characterization of a cryogenic ion trap system for the
implementation of quantum logic driven by near-field microwaves. The trap incorporates an on-chip
microwave resonator with an electrode geometry designed to null the microwave field component
that couples directly to the qubit, while giving a large field gradient for driving entangling logic
gates. We map the microwave field using a single 43Ca+ ion, and measure the ion trapping lifetime
and motional mode heating rates for one and two ions. |
