The Copenhagen interpretation, in which the core concepts are Heisenberg's uncertainty principle and nonlocal EPR correlation, has been long discussed. Second-order anticorrelation in a beam splitter represents the origin of these phenomena and cannot be achieved classically. Here, the anticorrelation of nonclassicality in a beam splitter is interpreted using the concept of coherence. Unlike the common understanding of photons having a particle nature, anticorrelation is rooted in the wave nature of coherence optics, described by coherence optics, wherein quantum superposition between two input fields plays a key role. This interpretation may pose fundamental questions about the nature of nonclassicality and pave a road to coherence-based quantum information.The Copenhagen interpretation, in which the core concepts are Heisenberg's uncertainty principle and nonlocal EPR correlation, has been long discussed.

Generation of correlated and anticorrelated multiple fields via atomic spin coherence

We report the experimental observation of generation of four and six strongly correlated and anticorrelated laser fields via atomic spin coherence in triple- and quadruple-\ensuremath{\Lambda}-type ${}^{85}$ Rb atomic systems. The anticorrelated Stokes and anti-Stokes fields, simultaneously produced through scattering of the applied laser fields off the atomic spin coherence established in advance by the coupling and probe fields, are also highly anticorrelated, respectively, with the corresponding scattering fields. This method can, in principle, be used to create correlated and anticorrelated narrowband multiple fields of any desired order with long correlation times. It paves the way to further study of the generation of multifield quantum correlations and anticorrelations of arbitrarily high order.We report the experimental observation of generation of four and six strongly correlated and anticorrelated laser fields via atomic spin coherence in triple- and quadruple-\ensuremath{\Lambda}-type ${}^{85}$Rb atomic systems.
