... Contextuality refers to when the result of an experiment depends on the context of the experiment. In quantum mechanics an example of this would be when measuring two observables, their measurements will depend on each other even though they commute. This means that the set-up of the system will inf ...

Quantification of Linear Entropy for Quantum Entanglement in He, H
... In the Appendix of this paper, we present the detailed results of Eq. (8) in terms of the I4 integrals. In [1,3,4], the authors solved this kind of four-electron integrals by carrying out the 12-dimensional integrals using Monte Carlo multidimensional numerical integration routines.
