... correlation in the DQDs, namely, the lower-lying bright exciton state is in fact polarized along the [11̅0] axis that is perpendicular to the elongation axis (i.e [110]) of each of the two QDs constituting the DQD as shown in Fig.2(b) and 2(d). This finding thus rules out the effect of the shape-ind ...

Via this embedding, we are able to retrieve, by measuring few observables, quantities that generally require full tomography in order to be evaluated. Moreover, we pay a special attention to the experimental feasibility, defining mappings wh ...

Two single-photon detectors collected the light at the two output ports of the beam splitter, while they changed the length of one of the arms before the beam splitter. When the lengths of the two arms matched perfectly, ...

Bell's theorem

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:
