Bell Nonlocality

Valerio Scarani

Abstract

Nonlocality was discovered by John Bell in 1964, in the context of the debates about quantum theory, but is a phenomenon that can be studied in its own right. Its observation proves that measurements are not revealing pre-determined values, falsifying the idea of “local hidden variables” suggested by Einstein and others. One is then forced to make some radical choice: either nature is intrinsically statistical and individual events are unspeakable, or our familiar space-time cannot be the setting for the whole of physics. As phenomena, nonlocality and its consequences will have to be predicted ... More

Keywords: Nonlocality, Bell’s theorem, John Bell, quantum entanglement, Einstein-Podolsky-Rosen, device-independent, quantum foundations, local hidden variables, local realism, spooky action
