Reflections on the quantum measurement paradox: A. J. Leggett
Basil J. Hiley, F. David Peat
Consideration of the classic measurement paradox of quantum mechanics raises the question: What is the relationship between acceptable theories of the physical world at different levels? It is suggested that it is similar to the relationship between maps of different types and that, while theories at different levels need not be derivable from one another, they must at least be mutually consistent in their predictions. The relationship between quantum mechanics, in its standard interpretation, and classical physics fails this test. Existing attempts to resolve the measurement paradox are briefly reviewed, and it is suggested that one avenue has been insufficiently explored; namely, the possibility that the complexity of a physical system may itself be a relevant variable which may introdu;ce new physical principles. Possible reasons for this lacuna are discussed, and it is pointed out that some of the relevant questions are now within the reach of an experimental test.
