Protective Measurement:A Paradigm Shift in Understanding Quantum Mechanics
protective measurement wave function expectation value physical state mass and charge distributions ergodic motion of a particle random discontinuous motion of particles measurement problem
2016/6/13
This article introduces the method of protective measurement and discusses its deep implications for the foundations of quantum mechanics. It is argued that protective measurement implies that the wav...
Quantum Superpositions and Causality:On the Multiple Paths to the Measurement Result
quantum superposition causality measurement problem
2016/6/12
The following analysis attempts to provide a general account of the multiple solutions given to the quantum measurement problem in terms of causality. Leaving aside instrumentalism which restricts its...
Quantum decoherence in a pragmatist view:Resolving the measurement problem
Measurement problem quantum theory pragmatist interpretation quantum fields
2016/5/30
This paper aims to show how adoption of a pragmatist interpretation permits a satisfactory resolution of the quantum measurement problem. The classic measurement problem dissolves once one recognizes ...
Huygens's 1688 Report to the Directors of the Dutch East India Company on the Measurement of Longitude at Sea and the Evidence it Offered Against Universal Gravity
Huygens, Newton, Universal Gravity, Longitude Research
2011/9/8
When Christiaan Huygens prepared the 1686/1687 expedition to the Cape of Good Hope on which his pendulum clocks were to be tested for their usefulness in measuring longitude at sea, he also gave instr...
Measurement Dependence is not Conspiracy: A Common Cause Model of EPR Correlations
Reichenbach´ s Principle of the Common Cause EPR Correlations
2009/6/18
In this paper I assess the adequacy of no-conspiracy conditions present in the usual derivations of the Bell inequality in the context of EPR correlations. First, I look at the EPR correlations from a...
Newtonian Emanation, Spinozism, Measurement, and the Baconian Origins of the Laws of Nature
Newton, Bacon, Spinoza, emanation, formal causation, laws of nature, measurement
2011/9/8
This paper investigates what Newton could have meant in a now famous passage from De Gravitatione (hereafter “DeGrav”) that “space is as it were an emanative effect of God” (21). First I offer a caref...
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...
This paper applies the ideas presented in "Time, Euclidean Geometry and Relativity" ID 1290 , to a specific problem in temporal measurement. It is shown that, under very natural assumptions, that if t...
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...
