  • S matrix from matrix product states 
    Vanderstraeten, Laurens; Haegeman, Jutho; Osborne, Tobias J.; Verstraete, Frank (College Park, MD : American Physical Society, 2014)

    In 1935, Einstein, Podolsky and Rosen (EPR) questioned the completeness of quantum mechanics by devising a quantum state of two massive particles with maximally correlated space and momentum coordinates. The EPR criterion ...
