The wave-particle duality dates back to Einstein's explanation of the photoelectric effect
through quanta of light and de Broglie's hypothesis of matter waves. Quantum mechanics …

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 …

Quantum mechanics is now a mature topic dating back more than a century. During its
scientific development, it fostered many technological advances that now are integrated into …

Entangled photon pairs are a critical resource in quantum communication protocols ranging
from quantum key distribution to teleportation. The current workhorse technique for …

We use entropic uncertainty relations to formulate inequalities that witness Einstein-
Podolsky-Rosen (EPR)-steering correlations in diverse quantum systems. We then use …

This book has been developed from an account of three lectures I gave at Princeton
University in October 2003 at the invitation of Princeton University Press. The title I had …

Quantum teleportation faces increasingly demanding requirements for transmitting large or
even entangled systems. However, knowledge of the state to be transmitted eases its …

Entanglement is nowadays considered as a key quantity for the understanding of
correlations, transport properties and phase transitions in composite quantum systems, and …

We demonstrate electromagnetic quantum states of single photons and of correlated photon
pairs exhibiting “hybrid” entanglement between spin and orbital angular momentum. These …

We present an entanglement purification protocol (EPP) to reconstruct some maximally
hybrid entangled states (HESs) from nonmaximally mixed HESs. We use simple linear …
