Is the universe exponentially complicated? A no-go theorem for hidden variable interpretations of quantum theory.
Speaker(s): Jonathan Barrett
Abstract: The quantum mechanical state vector is a complicated object. In particular, the amount of data that must be given in order to specify the state vector (even approximately) increases exponentially with the number of quantum systems. Does this mean that the universe is, in some sense, exponentially co... read more
