With the development of photonic quantum technologies, single photons have become key
for various applications including quantum communication and quantum computing …

Insights from spectroscopic experiments led to the development of quantum mechanics as
the common theoretical framework for describing the physical and chemical properties of …

Multiphoton interference reveals strictly nonclassical phenomena. Its applications range
from fundamental tests of quantum mechanics to photonic quantum information processing …

Wave-particle duality is strikingly illustrated by Wheeler's delayed-choice gedanken
experiment, where the configuration of a two-path interferometer is chosen after a single …

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 …

Quantum systems exhibit particle-or wavelike behavior depending on the experimental
apparatus they are confronted by. This wave-particle duality is at the heart of quantum …

With the emergence of the field of quantum communications, the appropriate choice of
photonic degrees of freedom used for encoding information is of paramount importance …

Traditionally, entanglement was considered to be a quirk of microscopic objects that defied a
common-sense explanation. Now, however, entanglement is recognized to be ubiquitous …

The counterintuitive features of quantum physics challenge many common-sense
assumptions. In an interferometric quantum eraser experiment, one can actively choose …

This book offers a discussion of Niels Bohr's conception of “complementarity,” arguably his
greatest contribution to physics and philosophy. By tracing Bohr's work from his 1913 atomic …
