Measurement: still a problem in standard quantum theory

Quantum Physics 2013-08-23 v2

Abstract

It is argued that recent claims by A. Hobson that standard quantum theory has no measurement problem cannot be sustained. Moreover, it is pointed out that taking the reduced density operator of a component system as an epistemic (ignorance-based) mixture has long been known to be untenable based on direct proof.
