在核磁共振实验和量子计算中，许多称为复合脉冲的脉冲(量子门)序列被开发出来，以抑制两个主要误差之一：脉冲长度误差和非共振误差。在本文中，我们描述了一种设计单量子比特级联复合脉冲(CCCP)的通用处方，该脉冲同时对两种类型的错误具有鲁棒性。为此，我们引入了一个新的性质，它被一些复合脉冲所满足，并且足以获得CCCP。然后介绍了一种设计执行时间更短、脉冲数更少的CCCP的通用方法。
In NMR experiments and quantum computation, many pulse (quantum gate) sequences called the composite pulses, were developed to suppress one of two dominant errors; a pulse length error and an off-resonance error. We describe, in this paper, a general prescription to design a single-qubit concatenated composite pulse (CCCP) that is robust against two types of errors simultaneously. To this end, we introduce a new property, which is satisfied by some composite pulses and is sufficient to obtain a CCCP. Then we introduce a general method to design CCCPs with shorter execution time and less number of pulses.
