US 2026/0245855 A1 · CAPACITIVE COUPLING COMPENSATION FOR DIRECT CURRENT ELECTRODES IN ION TRAPS

Abstract

An ion trap system and method of using an ion trap system, the system including a substrate, a radio frequency (RF) source configured to provide an RF signal, an RF electrode disposed in the substrate and connected to the RF source, a direct current (DC) source configured to provide a DC signal, a DC electrode disposed in the substrate and connected to the DC source, wherein the DC electrode is separate from the RF electrode, and a coupling compensation system configured to provide a compensating RF signal associated with the RF signal.
