چکیده

Individual laser-cooled 24Mg+ ions are confined in a linear Paul trap with a novel geometry where gold electrodes are located in a single plane and the ions are trapped 40 microm above this plane. The relatively simple trap design and fabrication procedure are important for large-scale quantum information processing (QIP) using ions. Measured ion motional frequencies are compared to simulations. Measurements of ion recooling after cooling is temporarily suspended yield a heating rate of approximately 5 motional quanta per millisecond for a trap frequency of 2.83 MHz, sufficiently low to be useful for QIP.

Toward scalable ion traps for quantum information processing

In this paper, we report the design, fabrication and preliminary testing of a 150 zone ion trap array built in a ‘surface-electrode’ geometry microfabricated on a single substrate. We demonstrate the transport of atomic ions between the legs of a ‘Y’-type junction and measure the in-situ heating rates for the ions. The trap design demonstrates the use of a basic component design library that ca...

Optimum electrode configurations for fast ion separation in microfabricated surface ion traps

For many quantum information implementations with trapped ions, effective shuttling operations are important. Here, we discuss the efficient separation and recombination of ions in surface ion trap geometries. The maximum speed of separation and recombination of trapped ions for adiabatic shuttling operations depends on the secular frequencies the trapped ion experiences in the process. Higher ...
