All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

The study of Gaussian states has arisen to a privileged position in continuous variable
quantum information in recent years. This is due to vehemently pursued experimental …

We propose a protocol for quantum illumination: a quantum-enhanced noise radar. A two-
mode squeezed state, which exhibits continuous-variable entanglement between so-called …

Provides fully updated coverage of new experiments in quantum optics This fully revised
and expanded edition of a well-established textbook on experiments on quantum optics …

We review the theory of continuous-variable entanglement with special emphasis on
foundational aspects, conceptual structures and mathematical methods. Much attention is …

Quantum discord, a measure of genuinely quantum correlations, is generalized to
continuous variable systems. For all two-mode Gaussian states, we calculate analytically the …

Using a superconducting circuit, the Josephson mixer, we demonstrate the first experimental
realization of spatially separated two-mode squeezed states of microwave light. Driven by a …

We prove that Gaussian operations are of no use for protecting Gaussian states against
Gaussian errors in quantum communication protocols. Specifically, we introduce a new …

We present a review of theoretical and experimental aspects of multiphoton quantum optics.
Multiphoton processes occur and are important for many aspects of matter–radiation …
