  • Relating to methods for digital to analogue converters in surface ion traps
    Patent number: 12489456
    Abstract: A surface ion trap comprising a plurality of electrodes and DACs, each electrode being controlled by a DAC, wherein a first set of DACs control the electrodes configured to trap an ion in a first area and a second set of DACs control the electrodes configured to trap an ion in a second area wherein the first set of DACs are configured to operate with low noise and low bandwidth and the second set of DACs are configured to operate with a high bandwidth and high noise.
