Electronic control of trapped-ion qubits offers a promising route towards a large-scale quantum computing processor. It has delivered some of the highest-fidelity quantum gates ever reported [1, 2] and is highly scalable as it allows integrating control signals directly into the trap chip. We present progress towards all-electronic control of trapped-ion qubits at Oxford Ionics, including a demonstration of high-fidelity two-qubit entangling gates with a duration of approximately 100 µs using an integrated microwave antenna. We thus reach the typical speed of laser-based gates in a highly scalable architecture.
