This review covers the latest developments in continuous-variable quantum-state
tomography of optical fields and photons, placing a special emphasis on its practical aspects …

A tomographic measurement is a ubiquitous tool for estimating the properties of quantum
states, and its application is known as quantum state tomography (QST). The process …

The counter-intuitive aspects of quantum physics have been for long illustrated by thought
experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now …

This book is a comprehensive survey of most of the theoretical and experimental
achievements in the field of quantum estimation of states and operations. Albeit still quite …

The irreversible evolution of a microscopic system under measurement is a central feature of
quantum theory. From an initial state generally exhibiting quantum uncertainty in the …

We construct a probabilistic quantum cloning machine by a general unitary-reduction
operation. With a postselection of the measurement results, the machine yields faithful …

Though quantum theory is celebrating its 100th anniversary this year, quan tum information
processing is still a remarkably young research field. The questions driving this research …

The quantum measurement problem, to wit, understanding why a unique outcome is
obtained in each individual experiment, is currently tackled by solving models. After an …

This paper sheds light on non-commutativity in quantum theory as regards theoretical
estimation. In it, we calculate the quantum Cramér-Rao-type bound for many cases, by use …
