摘要：
Mølmer-Sørensen（MS）门是离子阱中的一种双量子比特受控相位门，因其能够保持离子的运动状态而备受重视。然而，其保真度受到离子运动误差以及量子比特旋转误差的阻碍。在本工作中，我们提出了一种振幅调制的复合 MS 门，该门具有高保真度，对门定时、失谐和耦合误差具有鲁棒性，并且还能容忍交流斯塔克位移和漂移失谐误差。
英文摘要：
The Mølmer-Sørensen (MS) gate is a two-qubit controlled-phase 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 high fidelity robust to gate timing, detuning and coupling errors and is also tolerant of a.c. Stark shifts and drifting detuning errors.
