Preparing pseudo-pure states with controlled-transfer gates
arXiv:1003.2065 · doi:10.1103/PhysRevA.82.032315
Abstract
The preparation of pseudo-pure 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 pseudo-pure states to be prepared efficiently using spatial averaging techniques.
