精确的量子控制是实现量子通信、量子计算等量子信息处理的关键技术。事实上，受控的量子态会遭受系统误差引起的不良影响。复合脉冲（CP）用于消除控制过程中系统误差的影响。单量子位控制是量子控制中最基本的控制，它通常受到两种误差的影响：脉冲长度误差和偏共振误差（ORE）。在本文中，我们关注 ORE-robust CP，并系统地构建包含三个基本操作的对称 CP，以了解它们的属性。我们找到了无限多的 ORE-robust CP，包括著名的 CORPSE 系列，并根据门不保真度和操作时间来评估它们的性能，这两者对于实现精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 and off-resonance error (ORE). In this paper, we focus on ORE-robust CPs and systematically construct symmetric ones comprising three elementary operations in order to understand their properties. We find an infinitely large number of ORE-robust CPs, including the well-known CORPSE family, and evaluate their performance according to gate infidelity and operation time, both of which are important for the realization of accurate quantum control.
