Complementarity and Entanglement in Quantum Information Theory

摘要: The restrictions that nature places on the distribution of correlations in a multipartite quantum system play fundamental roles evolution such systems, and yield vital insights into design protocols for control ensembles with potential applications field computing. We show how this entanglement sharing behavior may be studied increasingly complex systems both theoretical experimental significance demonstrate sharing, as well other unique features entanglement, e.g. fact maximal information about does not necessarily entail its component subsystems, understood specific consequences phenomenon complementarity extended to composite systems. also present local hidden-variable model supplemented by an efficient amount classical communication reproduces quantum-mechanical predictions entire class Gottesman-Knill circuits. success our simulation provides strong evidence power computation arises directly from but rather nonexistence efficient, realistic description computation, even when augmented nonlocal, communication. Finally, we note findings presented thesis support conjecture Hilbert space dimension is objective property since it constrains number valid conceptual divisions subsystems.
