Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

Quantum networks providing shared entanglement over a mesh of quantum nodes will
revolutionize the field of quantum information science by offering novel applications in …

Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

Quantum mechanics has irked physicists ever since its conception more than 100 years ago.
While some of the misgivings, such as it being unintuitive, are merely aesthetic, quantum …

In a Bell experiment, it is natural to seek a causal account of correlations wherein only a
common cause acts on the outcomes. For this causal structure, Bell inequality violations can …

Spin correlations of Λ-hyperons embedded in the QCD strings formed in high energy collider
experiments provide unique insight into their locality and entanglement features. We show …

Bell's theorem rules out many potential reformulations of quantum mechanics, but within a
generalized framework it does not exclude all locally mediated models. Such models …

Among the known particles, the neutron is special because it provides experimental access
to all of the four fundamental forces and a wide range of hypothetical interactions. Despite …

Inspired by the recent remarkable progress in the experimental test of local realism, we
report here such a test that achieves an efficiency greater than (78%) 2 for entangled photon …

Bell's theorem is typically understood as the proof that quantum theory is incompatible with
local-hidden-variable models. More generally, we can see the violation of a Bell inequality …
