"Clearly, to read out all the components of $\vec x$ would require one to perform the procedure at least $N$ times. However, often one is interested not in $\vec x$ itself, but in some expectation calue $\vec x^T M\vec x$, where $M$ is some linear operator (our procedure also accommodates nonlinear operators as described below)." | |
