Robust composite Molmer-Sorensen gate — •Kaloyan Zlatanov, Svetoslav Ivanov, and Nikolay Vitanov — Center for Quantum Technologies, Sofia, Bulgaria

The Mølmer-Sørensen (MS) gate is a two-qubit rotational gate in ion traps that is highly valued due to its ability to preserve the motional state of the ions. However, its fidelity is obstructed by errors affecting the motion of the ions as well as the rotation of the qubits. In this work, we propose an amplitude-modulated composite MS gate which features fidelity which is robust to gate timing, detuning and coupling errors.
