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 …

Quantum Mechanics (QM) is one of the pillars of modern physics: an impressive amount of
experiments have confirmed this theory and many technological applications are based on …

Photonic quantum technology can be enhanced by monolithic fabrication of both the
underpinning quantum hardware and the corresponding electronics for classical readout …

We present a detailed experimental analysis of a free-propagating light pulse prepared in a
“Schrödinger kitten” state, which is defined as a quantum superposition of “classical” …

The state of a microscopic system encodes its complete quantum description, from which the
probabilities of all measurement outcomes are inferred. Being a statistical concept, the state …

We experimentally demonstrate that the entanglement between Gaussian entangled states
can be increased by non-Gaussian operations. Coherent subtraction of single photons from …

We present generation of photon-subtracted squeezed states at 860 nm, from nearly pure,
continuous-wave squeezed vacua generated with a periodically-poled KTiOPO_4 crystal as …

We report the experimental realization and tomographic analysis of quantum light states
obtained by exciting a classical thermal field by a single photon. Such states, although …

We perform state tomography of an itinerant squeezed state of the microwave field prepared
by a Josephson parametric amplifier (JPA). We use a second JPA as a preamplifier to …

Unique in that it is jointly written by an experimentalist and a theorist, this monograph
presents universal quantum computation based on quantum teleportation as an elementary …
