Extended Data Fig. 5: Trap detachment.
Schematic of the switch arrangement used to detach a trap electrode from the external DAC. Three MOSFET-based switches with an on-state resistance of 11 Ω and off-state capacitance Coff = 0.45 pF are chained and interleaved with capacitors C = 560 pF, forming capacitive dividers for improved isolation at radio frequencies. The voltage last applied by the DAC is retained by the combined capacitance of the trap electrode and an RC filter(R = 1 kΩ, C = 560 pF) placed within the vacuum apparatus.
