Minimax estimation of the Wigner function in quantum homodyne tomography with ideal detectors
Madalin Guta, Luis Artiles
We estimate the quantum state of a light beam from results of quantum homodyne measurements performed on identically prepared pulses. The state is represented through the Wigner fu…
Optimal estimation of qubit states with continuous time measurements
Madalin Guta, Bas Janssens, Jonas Kahn
We propose an adaptive, two steps strategy, for the estimation of mixed qubit states. We show that the strategy is optimal in a local minimax sense for the trace norm distance as w…
Optimal cloning of mixed Gaussian states
Madalin Guta, Keiji Matsumoto
We construct the optimal 1 to 2 cloning transformation for the family of displaced thermal equilibrium states of a harmonic oscillator, with a fixed and known temperature. The tran…
Local asymptotic normality in quantum statistics
Madalin Guta, Anna Jencova
The theory of local asymptotic normality for quantum statistical experiments is developed in the spirit of the classical result from mathematical statistics due to Le Cam. Roughly…
