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…
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…
An invitation to quantum tomography (II)
L. M. Artiles, R. D. Gill, M. I. Guta
The quantum state of a light beam can be represented as an infinite dimensional density matrix or equivalently as a density on the plane called the Wigner function. We describe qua…
An invitation to quantum tomography
Richard Gill, Madalin Guta
We describe quantum tomography as an inverse statistical problem and show how entropy methods can be used to study the behaviour of sieved maximum likelihood estimators. There rema…
