A method of performing a computation using a quantum computer includes generating a first laser pulse and a second laser pulse to cause entanglement interaction between a first trapped ion and a second trapped ion of a plurality of trapped ions that are aligned in a first direction, each of the plurality of trapped ions having two frequency-separated states defining a qubit, and applying the generated first laser pulse to the first trapped ion and the generated second laser pulse to the second trapped ion. Generating the first laser pulse and the second laser pulse includes stabilizing the entanglement interaction between the first and second trapped ions against fluctuations in frequencies of collective motional modes of the plurality of trapped ions in a second direction that is perpendicular to the first direction. 一种使用量子计算机执行计算的方法，该方法包括：生成第一激光脉冲和第二激光脉冲以产生沿第一方向排列的多个囚禁离子中的第一囚禁离子和第二囚禁离子之间的纠缠相互作用，所述多个囚禁离子中的每一个具有定义量子比特的两个频率分离状态；以及将生成的第一激光脉冲施加到第一囚禁离子，并将生成的第二激光脉冲施加到第二囚禁离子。生成第一激光脉冲和第二激光脉冲包括针对所述多个囚禁离子在垂直于第一方向的第二方向
