Firstly, we control the phase of the laser field at the ion position using a free-space phase-stable standing wave and show how to coherently suppress a non-computing error source in the conventional Mølmer-Sørensen (MS) interaction. This approach allows us to break the fundamental speed limit in standard MS gates. Secondly, we present our experimental work on utilising non-commuting terms to create two-qubit entanglement suitable for optical, metastable, and ground state qubit encodings [1].
