    "abstract": "Optimal and finite positive operator valued measurements on a finite number\n$N$ of identically prepared systems have been presented recently. With physical\nrealization in mind we propose here optimal and minimal generalized quantum\nmeasurements for two-level systems.\n  We explicitly construct them up to N=7 and verify that they are minimal up to\nN=5. We finally propose an expression which gives the size of the minimal\noptimal measurements for arbitrary $N$.",
