Microtrap Fabrication Technology for
Trapped Ion Quantum Information Science

Ion Shuttling:
Fast ion shuttling between different regions (eg processor and memory registers) of a trapped ion array without loss of coherence constitutes one of the primary routes to QIP incorporating remote registers. Siegen have developed single-channel fast FPGA controlled DAC prototype for fast ion shuttling:

• 50 MHz update rate demonstrated
• Scalable to 100 channels
• Each electrode will have DAC, each DAC own memory
• DAC array controlled by multiple FPGAs
• Motherboard / daughterboard approach to facilitate expansion
