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 …

Bell's 1964 theorem, which states that the predictions of quantum theory cannot be
accounted for by any local theory, represents one of the most profound developments in the …

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 …

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

Quantum information processing is the emerging field that defines and realizes computing
devices that make use of quantum mechanical principles such as the superposition …

We show that there are Bell-type inequalities for noncontextual theories that are violated by
any quantum state. One of these inequalities between the correlations of compatible …

We discuss general Bell inequalities for bipartite and multipartite systems, emphasizing the
connection with convex geometry on the mathematical side, and the communication aspects …

Quantum information processing is at the crossroads of physics, mathematics and computer
science. It is concerned with what we can and cannot do with quantum information that goes …

A proof of Bell's theorem without inequalities valid for both inequivalent classes of three-
qubit entangled states under local operations assisted by classical communication, namely …

A bipartite perfect quantum strategy (BPQS) allows two players who cannot communicate
with each other to always win a nonlocal game. BPQSs are rare but fundamental in light of …
