The Age of EntanglementBy: Louisa Gilder In The Age of Entanglement, Louisa Gilder brings to life one of the pivotal debates in twentieth century physics. In 1935, Albert Einstein famously showed that, according to the quantum theory, separated particles could act as if intimately connecteda phenomenon which he derisively described as spooky action at a distance. In that same year, Erwin Schrdinger christened this correlation entanglement. Yet its existence was mostly
