High-fidelity quantum logic gates using trapped-ion hyperfine qubits — mentioned by Strilanc

> The [two qubit] gates are about as reliable as any others you will find in the quantum computing world, which is to say that operations complete successfully around 93 percent of the time. For comparison, ion-based quantum computers are at 95 to 99 percent and superconducting quantum computers are around 90 to 95 percent. [...] Those comparison numbers are incorrect. Ion-based and superconducting-based groups have reported two-qubit gate fidelities of 99.9% [1] and 99.4% [2] respectively. [1]: https://arxiv.org/abs/1512.04600 [2]: https://arxiv.org/abs/1402.4848
