How Albert Einstein invented entanglement despite his intention
... considered to be an instantaneous ‘action at a distance’. For Einstein such an instantaneousity was impossible because it violated the limitation of the constant speed of light c, fundamental for his theories of relativity. Therefore he called quantum entanglement derogatively a ‘spooky action at a ...

Spin Squeezing on an Atomic Clock Transition.
... Spin squeezing requires a Hamiltonian that is at least quadratic in the spin components, or equivalently, some form of interaction between the particles. While it is possible to use interatomic collisions in a Bose-Einstein condensate (BEC) for that purpose,14,15 these density-dependent interactions ...

Limitations on the superposition principle: superselection
... Given that the probabilities associated with the states (1) and (2) differ, that is, as h9|9i 6= h9 0 |9 0 i, the superposition becomes essentially different from the original state after the 2π rotation. This implies that a superposition of the form (1) is devoid of physical meaning unless ap = 0 o ...

Enhancement of quantum dot peak-spacing fluctuations

Bell's theorem
.svg?width=300)
Bell's theorem is a ‘no-go theorem’ that draws an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. This theorem is named after John Stewart Bell.In its simplest form, Bell's theorem states:Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from ""indifference"" to ""wild extravagance"". Lawrence Berkeley particle physicist Henry Stapp declared: ""Bell's theorem is the most profound discovery of science.""Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables). Bell concluded:Bell summarized one of the least popular ways to address the theorem, superdeterminism, in a 1985 BBC Radio interview:
