Local asymptotic normality for qubit states
Madalin Guta, Jonas Kahn
We consider n identically prepared qubits and study the asymptotic properties of the joint state ρ^{\otimes n}. We show that for all individual states ρsituated in a local neighbor…

Minimax and adaptive estimation of the Wigner function in quantum homodyne tomography with noisy data
Cristina Butucea, Madalin Guţa, Luis Artiles
We estimate the quantum state of a light beam from results of quantum homodyne measurements performed on identically prepared quantum systems. The state is represented through the…
