Abstract
A scalable, multiplexed ion trap for quantum information processing is fabricated and tested. The trap design and fabrication process are optimized for scalability to small trap size and large numbers of interconnected traps, and for integration of control electronics and optics. Multiple traps with similar designs are tested with [superscript 111]Cd[superscript +], [superscript 25]Mg[superscript +], and [superscript 88]Sr[superscript +] ions at room temperature and with [superscript 88]Sr[superscript +] at 6 K, with respective ion lifetimes of 90 s, 300 ± 30 s, 56 ± 6 s, and 4.5 ± 1.1 hours. The motional heating rate for [superscript 25]Mg[superscript +] at room temperature and a trap frequency of 1.6 MHz is measured to be 7 ± 3 quanta per millisecond. For [superscript 88]Sr[superscript +] at 6 K and 540 kHz the heating rate is measured to be 220 ± 30 quanta per second.
