论文摘要
准确的量子控制是实现量子信息处理的关键技术，例如量子通信和量子计算。实际上，控制下的量子状态遭受了系统错误引起的不良影响。复合脉冲（CP）用于消除对照过程中系统误差的影响。一个量子控制是量子控制中最基本的一个量子控制，通常受两个错误的影响：脉冲长度误差（PLE）和异位误差（ore）。在这项研究中，我们专注于矿石射击的CP，并系统地构建具有三个基本操作的矿石射击对称CP。我们发现无限数量的矿石CP，并根据门的不忠和操作时间评估其性能，这两个对于实现准确的量子控制都很重要。
Accurate quantum control is a key technology for realizing quantum information processing, such as quantum communication and quantum computation. In reality, a quantum state under control suffers from undesirable effects caused by systematic errors. A composite pulse (CP) is used to eliminate the effects of systematic errors during control. One qubit control, which is the most fundamental in quantum control, is typically affected by two errors: pulse length error (PLE) and off-resonance error (ORE). In this study, we focus on ORE-robust CPs and systematically construct ORE-robust symmetric CPs with three elementary operations. We find an infinitely large number of ORE-robust CPs and evaluate their performance according to gate infidelity and operation time, both of which are important for the realization of accurate quantum control.
