Quantum Darwinism and spectrum broadcast structure describe the emergence of objectivity in quantum systems. However, it is… Expand The objective, classical world emerges from the underlying quantum substrate via the proliferation of redundant copies of… Expand A state selected at random from the Hilbert space of a many-body system is overwhelmingly likely to exhibit highly non-classical… Expand We study quantum Darwinism, the redundant recording of information about the preferred states of a decohering system by its… Expand Observers restricted to the observation of pointer states of apparatus cannot conclusively demonstrate that the pointer of an… Expand Quantum Darwinism describes the proliferation, in the environment, of multiple records of selected states of a quantum system. It… Expand Quantum Darwinism provides an information-theoretic framework for the emergence of the objective, classical world from the… Expand
Starting with basic axioms of quantum theory I revisit "Relative State Interpretation'' set out 50 years ago by Hugh Everett.
As quantum information science approaches the goal of constructing quantum computers, understanding loss of information through… Expand Effective classicality of a property of a quantum system can be defined using redundancy of its record in the environment. This… Expand
