Quantum Measurements, Propensities and the Problem of Measurement
quantum mechanics problem of measurement
2008/4/22
This paper expands on, and provides a qualified defence of, Arthur Fine’s selective interactions solution to the measurement problem. Fine’s approach must be understood against the background of the i...
Reality, measurement and locality in Quantum Field Theory
Quantum Field Theory Standard Model Correlations Locality
2008/4/22
It is currently believed that the local causality of Quantum Field
Theory (QFT) is destroyed by the measurement process. This belief
is also based on the Einstein-Podolsky-Rosen (EPR) paradox and on...
Non-collapse theories of quantum mechanics have the peculiar characteristic that, although their measurements produce definite results, their state vectors remain in a superposition of possible outcom...
Solving the measurement problem: de Broglie-Bohm loses out to Everett
de Broglie-Bohm Everett measurement problem
2008/4/21
The quantum theory of de Broglie and Bohm solves the measurement problem, but the hypothetical corpuscles play no role in the argument. The solution finds a more natural home in the Everett interpreta...
This is a preliminary version of an article to appear in the forthcoming Ashgate Companion to the New Philosophy of Physics.In it, I aim to review, in a way accessible to foundationally interested phy...
On the measurement problem for a two-level quantum system
measurement problem Born rule Berry's phase
2008/4/15
A geometric approach to quantum mechanics with unitary evolution and non-unitary collapse processes is developed. In this approach the Schroedinger evolution of a quantum system is a geodesic motion o...
The kinds of models discussed in this paper function as measuring instruments. We will concentrate on two necessary steps for measurement: (1) the search of a mathematical representation of the phenom...
Measurement Outcomes and Probability in Everettian Quantum Mechanics
Everett interpretation Many worlds
2008/4/15
The decision-theoretic account of probability in the Everett or many-worlds interpretation, advanced by David Deutsch and David Wallace, is shown to be circular. Talk of probability in Everett presume...
How Bohm’s Theory Solves the Measurement Problem
Bohm Everett hidden variables many worlds
2008/4/14
I examine recent arguments based on functionalism that claim to show that Bohm’s theory fails solve the measurement problem, or if it does so, it is only because it reduces to a form of the many-world...
About conditional probabilities of events regarding the quantum mechanical measurement process
Heisenberg Principle Measurement process
2008/4/9
We consider the successive measurement of position and momentum of a single particle. Let P be the conditional probability to measure the momentum with precision dk, given a previously successful posi...
A Quantum Mechanical Measurement Leading to Simultaneous Spin-Up and Spin-Down State of a Single Electron
Quantum Mechanics Singlet State Two Spin-1/2 Particles
2008/4/9
In is shown that when two observers carry out a simultaneous measurement on a pair of spin-? particles in a "singlet" state a possibility exists for an outcome that lacks physical meaning. More specif...
This paper outlines a ‘paradox’ in quantum measurement theory, illustrated with two different types of systems. If this paradox cannot be resolved in ordinary quantum mechanics (as I currently think),...
