The science of quantum information has arisen over the last two decades centered on the
manipulation of individual quanta of information, known as quantum bits or qubits. Quantum …

Quantum information is a rapidly advancing area of interdisciplinary research. It may lead to
real-world applications for communication and computation unavailable without the …

Quantum Continuous Variables introduces the theory of continuous variable quantum
systems, from its foundations based on the framework of Gaussian states to modern …

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 …

Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

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” …

We perform a review of various approaches to the implementation of quantum memories,
with an emphasis on activities within the quantum memory sub-project of the EU integrated …

In recent years it has been recognized that properties of physical systems such as
entanglement, athermality, and asymmetry, can be viewed as resources for important tasks …

Quantum optical Gaussian states are a type of important robust quantum states which are
manipulatable by the existing technologies. So far, most of the important quantum …

The recent launch of the Micius quantum-enabled satellite heralds a major step forward for
long-range quantum communication. Using single-photon discrete-variable quantum states …
