Decoherence, the Classical Appearance of the Quantum World and Quantum Evolution

Bradley Dean Lignoski

The motivation for this project was the provocative new theory of the quantum evolution of life proposed by McFadden and others. To understand the theory, one must first understand how the world appears classical though it is governed by quantum rules. Decoherence theory provides an observer free alternative to the controversial "wave function collapse" postulate. This thesis provides an illuminating introduction into decoherence theory and its possible application to the origin and evolution of life.
