Conceptual Problems

Decoherence is widely felt to have something to do with the quantum measurement problem, but getting clear on just what is made difficult by the fact that the ‘measurement problem’, as traditionally presented in foundational and philosophical discussions, has become somewhat disconnected from the conceptual problems posed by real physics. This, in turn, is because quantum mechanics as discussed in textbooks and in foundational discussions has become somewhat removed from scientific practice, especially where the analysis of measurement is concerned. This paper has two goals: firstly (§§1–2), to present an account of how quantum measurements are actually dealt with in modern physics (hint: it does not involve a collapse of the wave function) and to state the measurement problem from the perspective of that account; and secondly (§§3–4), to clarify what role decoherence plays in modern measurement theory and what effect it has on the various strategies that have been proposed to solve the measurement problem.

Abstract The article explores the so-called quantum measurement problem, or the collapse of a wave function in the act of observation, as a reading and interpretive strategy. In particular, the article argues that the Maltese falcon, if it exists at all, does not exist in Dashiell Hammett's noir version of San Francisco until Sam Spade attempts to find it in a particular place. Further, reading from a quantum perspective suggests that Casper Gutman does not really want to find the jewel-encrusted statuette, or one would have appeared more often. Drawing on the work of Niels Bohr, Erwin Schrödinger, Henry P. Stapp, and other quantum physicists, the article explores the role that consciousness and acts of observation play in the calling into being of material reality as it is imagined in narrative fiction.

This extended note deals with a pedagogical description of the entangled state of two particles, starting from first principles. After some general remarks about quantum mechanics and physical theories, the single particle case is discussed by defining state, uncertainty relations and wave function in the state space. The system of two particles is then considered, with its possible states, starting from the original papers by Einstein Podolsky Rosen and by Schroedinger. The quantum measurement problem is then introduced, together with its role in the entanglement state. Finally the orthodox solution and the relevant conclusions are drawn.
