    "abstract": "I exploit the formal equivalence between the ground state of a $d$\ndimensional quantum system and a d+1 dimensional classical Ising chain to\nrepresent quantum entanglement in terms of classical correlations only. This\noffers a general \"local hidden variable model\" for all quantum phenomena\nexisting in one dimension lower than the (hidden variable) classical model\nitself. The local hidden variable model is not contradicted by the implications\nof Bell\u0027s theorem. Formal theory is presented first and then exemplified by the\nquantum Ising spin chain in a transverse magnetic field. Here I explicitely\nshow how to derive any two site entanglement in the transverse model from the\npartition function of the classical Ising spin chain existing in two\ndimensions. Some speculations are then presented regarding possible fundamental\nimplications of these results.",
