In a landmark series of papers Wojciech Zurek offers an
explanation of the relationship between quantum and classical
realities resolving the debate between Einstein and Bohr, perhaps the
most famous scientific debate in history. Einstein insisted there must
be an objective reality existing independent of the observations we
choose to make while Bohr insisted it is wrong to
think the task of physics is to find out how Nature is, physics concerns
only what we can say about Nature.
As might be expected they both turn out to be
partially right! Einstein, who many considered unreasonably
cranky in his objections to quantum theory, is largely
vindicated by Zurek's thorough explanation of the circumstances
under which quantum phenomena result in objective reality.
Perhaps the most unforeseen aspect of Zurek's findings is a
Darwinian process he coins Quantum Darwinism, responsible for
selecting classical reality from quantum reality.
Zurek presents his most recent results and
theoretical summary in his most recent paper:
Relative States and the Environment Einselection, Envariance,
Quantum Darwinism, and the Existential Interpretation.
design space in which evolution operates is unimaginably huge and must
ultimately correlate to the Hilbert space in which the universe's
quantum state vector evolves. How the limitless potentialities of this
quantum space are reduced to the more manageable classical space of
possibilities witnessed by objective observers has long puzzled
thoughtful researchers. Now in a series of ground breaking papers
Wojciech Zurek and other researchers have outlined a
process called 'Quantum Darwinism' that they claim can manage this feat.
Wojciech Hubert Zurek is a well-known
scientist in the study of physics. Laboratory Fellow at Los Alamos
National Laboratory. A leading authority on quantum theory, especially
decoherence, among other physics topics. His work also has a lot of
potential benefit to the emerging field of quantum computing.
