Abstract

The dominant error sources for state-of-the-art implementations of laser-free trapped-ion entangling gates are decoherence of the qubit state and motion. The gate error from these decoherence mechanisms can be suppressed with additional control fields, or with more phase space loops, the latter at a cost in gate speed. Here, we propose a laser-free gate that is simultaneously resilient to both types of decoherence and does not require additional control fields.
