Abstract

We demonstrate a trapped ion entangling gate scheme proposed by Bermudez et~al [Phys. Rev. A 85, 040302 (2012)]. Simultaneous excitation of a strong carrier and a single sideband transition enables deterministic creation of entangled states. The method works for magnetic field-insensitive states, is robust against thermal excitations, includes dynamical decoupling from qubit dephasing errors, and provides simplifications in experimental implementation compared to some other entangling gates with trapped ions. We achieve a Bell state fidelity of 0.974(4) and identify the main sources of error.
