Quantum technologies exploit entanglement to revolutionize computing, measurements, and
communications. This has stimulated the research in different areas of physics to engineer …

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 …

More than 50 years ago, John Bell proved that no theory of nature that obeys locality and
realism can reproduce all the predictions of quantum theory: in any local-realist theory, the …

Local realism is the worldview in which physical properties of objects exist independently of
measurement and where physical influences cannot travel faster than the speed of light …

We present a loophole-free violation of local realism using entangled photon pairs. We
ensure that all relevant events in our Bell test are spacelike separated by placing the parties …

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 …

Superposition, entanglement and non-locality constitute fundamental features of quantum
physics. The fact that quantum physics does not follow the principle of local causality,–can …

In the field of quantum simulation, methods and tools are explored for simulating the
dynamics of a quantum system of interest with another system that is easier to control and …

After they have interacted, quantum particles generally behave as a single nonseparable
entangled system. The concept of entanglement plays an essential role in quantum physics …

Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …
