This paper presents an all-electronic control architecture for trapped-ion quantum computers (TIQCs) that enables high-fidelity, scalable quantum gate operations. The system uses a microfabricated chip with shared current-carrying traces and local tuning electrodes to perform low-noise, site-selective single- and two-qubit gates. The architecture leverages AC magnetic fields from shared traces and DC electric fields from local electrodes to achieve precise control over qubit interactions. The system was experimentally validated using a seven-zone ion trap, where single-qubit gates achieved 99.99916(7)% fidelity and two-qubit gates achieved 99.97(1)% fidelity. The system demonstrated consistent performance across the device with minimal crosstalk and long-term stability. The architecture offers a path to large-scale quantum computing by combining the low-noise performance of atomic qubits with the scalability of chip-integrated electronics. The system is compatible with standard microfabrication processes and allows for efficient control of qubit states through local tuning. The results demonstrate the feasibility of high-fidelity, scalable quantum computing using all-electronic control of trapped-ion qubits. The paper also discusses the potential for further scaling of the system to mid-scale quantum computers with thousands of qubits, and highlights the advantages of the all-electronic approach over traditional laser-based methods. The architecture is expected to enable the development of next-generation high-performance quantum computers with many thousands of qubits.This paper presents an all-electronic control architecture for trapped-ion quantum computers (TIQCs) that enables high-fidelity, scalable quantum gate operations.
