Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

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 …

Quantum networks provide opportunities and challenges across a range of intellectual and
technical frontiers, including quantum computation, communication and metrology. The …

Optical microcavities confine light to small volumes by resonant recirculation. Devices based
on optical microcavities are already indispensable for a wide range of applications and …

This book offers a systematic and comprehensive exposition of the quantum stochastic
methods that have been developed in the field of quantum optics. It includes new treatments …

Two decades after their demonstration, superconducting nanowire single-photon detectors
(SNSPDs) have become indispensable tools for quantum photonics as well as for many …

How can one prove that a given quantum state is entangled? In this paper we review
different methods that have been proposed for entanglement detection. We first explain the …

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 …

Written in a clear pedagogic style, this book deals with the application of density matrix
theory to atomic and molecular physics. The aim is to precisely characterize sates by a …

Quantum communication relies on the availability of light pulses with strong quantum
correlations among photons. An example of such an optical source is a single-photon pulse …
