    "abstract": "We exhibit measurements for optimal state estimation which have a finite\nnumber of outcomes. This is achieved by a connection between finite optimal\nmeasurements and Gauss quadratures. The example we consider to illustrate this\nconnection is that of state estimation on $N$ qubits, all in a same pure state.\nExtensions to state estimation of mixed states are also discussed.",
