    "abstract": "The optimal estimation of a quantum mechanical 2-state system (qubit) - with\nN identically prepared qubits available - is obtained by measuring all qubits\nsimultaneously in an entangled basis. We report the experimental estimation of\nqubits using a succession of N measurements on individual qubits where the\nmeasurement basis is changed during the estimation procedure conditioned on the\noutcome of previous measurements (self-learning estimation). The performance of\nthis adaptive algorithm is compared with other algorithms using measurements in\na factorizing basis.",
