Consistent quantum theory is a theoretical framework that aims to reconcile the principles of quantum mechanics with the concept of determinism. It proposes that the randomness and indeterminacy observed in quantum systems is a result of our limited understanding and measurement capabilities, rather than an inherent property of the universe.
The consistent quantum theory was first proposed by physicist Robert B. Griffiths in the late 1980s. He published his ideas in a series of papers and later in his book "Consistent Quantum Theory" in 2002.
Traditional quantum mechanics follows the Copenhagen interpretation, which states that the wave function of a quantum system collapses into a single state upon measurement, and the outcome of the measurement is probabilistic. In contrast, consistent quantum theory proposes that the wave function always evolves deterministically, and the appearance of probability is a result of our limited knowledge and measurement process.
The consistent quantum theory has significant implications for our understanding of the fundamental nature of reality. It challenges the notion of randomness and indeterminacy in quantum mechanics and suggests a more deterministic view of the universe. It also has implications for the potential development of new technologies, such as quantum computing.
Currently, there is no direct experimental evidence to support consistent quantum theory. However, it has gained significant attention and interest among physicists, and many ongoing experiments are exploring its predictions. Some interpretations of existing quantum experiments also align with the principles of consistent quantum theory, providing some indirect evidence for its validity.
