A central result in the foundations of quantum mechanics is the Kochen-Specker theorem. In
short, it states that quantum mechanics is in conflict with classical models in which the result …

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

In this review article we discuss the present status of direct nuclear reactions and the nuclear
structure aspects one can study with them. We discuss the spectroscopic information we can …

Background: Recent advances in nuclear structure theory have led to the availability of
several complementary ab initio many-body techniques applicable to light and medium …

Holography is a cornerstone characterization and imaging technique that can be applied to
the full electromagnetic spectrum, from X-rays to radio waves or even particles such as …

It is impossible to unambiguously distinguish the four Bell states in polarization, resorting to
linear optical elements only. Recently, the hyperentangled Bell state, the simultaneous …

Entanglement purification is a very important element for long-distance quantum
communication. Different from all the existing entanglement purification protocols (EPPs) in …

The phenomenon of entanglement marks one of the furthest departures from classical
physics and is indispensable for quantum information processing. Despite its fundamental …

Entanglement is one of the most fascinating properties of quantum mechanical systems;
when two particles are entangled the measurement of the properties of one of the two allows …

Nearly all protocols requiring shared quantum information—such as quantum teleportation
or key distribution—rely on entanglement between distant parties. However, entanglement is …
