    "abstract": "We give an explicit procedure based on entangled input states for estimating\na $SU(d)$ operation $U$ with rate of convergence $1/N^2$ when sending $N$\nparticles through the device. We prove that this rate is optimal. We also\nevaluate the constant $C$ such that the asymptotic risk is $C/N^2$. However\nother strategies might yield a better const ant $C$.",
