On the Topological Origin of Entanglement in Ising Spin Glasses
... case are those of the quantum spins on a 2D square sub-lattice of the original 3D lattice whose third dimension acts as the discretised time direction. To summarise, the reduced density matrices that one is interested in, both for thermal and quantum entanglement, are expressed in terms of topologic ...

The Problem of Confirmation in the Everett Interpretation
... One of the most striking features of quantum theory is that systems can be in superpositions of states normally thought to be mutually exclusive. Moreoever, the time-dependent Schrodinger’s equation implies that quantum systems undergo linear, deterministic evolution. This means that in any measurem ...

Heralded atomic-ensemble quantum memory for photon polarization states
... Figure 2. (a) Set-up. The storage of a photon of arbitrary polarization from the write beam is heralded by a photon detected on single-photon counter D1. Small arrows indicate beam polarization and OP is the optical pumping beam. NPBS, PBS, QWP and HWP denote a non-polarizing beamsplitter, a polariz ...

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:
