赝纯态的制备在高温系综系统中实现量子信息处理（如核磁共振）中起着核心作用。在这里，我们描述了一个简单的方法，基于受控传输门，允许伪纯态准备有效地使用空间平均技术。
The preparation of pseudopure states plays a central role in the implementation of quantum information processing in high-temperature ensemble systems, such as nuclear magnetic resonance. Here we describe a simple approach based on controlled-transfer gates which permits pseudopure states to be prepared efficiently using spatial averaging techniques.
