Аннотация:We report an experimental realization of an adaptive quantum state tomography protocol. Our method takes
advantage of a Bayesian approach to statistical inference and is naturally tailored for adaptive strategies. For
pure states, we observe close to N
−1
scaling of infidelity with overall number of registered events, while the best
nonadaptive protocols allow for N
−1/2
scaling only. Experiments are performed for polarization qubits, but the
approach is readily adapted to any dimension
