Predictability sieve, pointer states, and the classicality of quantum trajectories
Diego A. R. Dalvit, Jacek Dziarmaga, Wojciech H. Zurek
We study various measures of classicality of the states of open quantum systems subject to decoherence. Classical states are expected to be stable in spite of decoherence, and are…
Decoherence from spin environments
F. M. Cucchietti, J. P. Paz, W. H. Zurek
We examine two exactly solvable models of decoherence -- a central spin-system, (i) with and (ii) without a self--Hamiltonian, interacting with a collection of environment spins. I…
Sub-Planck phase-space structures and Heisenberg-limited measurements
F. Toscano, D. A. R. Dalvit, L. Davidovich +1
We show how sub-Planck phase-space structures in the Wigner function can be used to achieve Heisenberg-limited sensitivity in weak force measurements. Nonclassical states of harmon…
Quantum Darwinism: Entanglement, branches, and the emergent classicality of redundantly stored quantum information
Robin Blume-Kohout, W. H. Zurek
We lay a comprehensive foundation for the study of redundant information storage in decoherence processes. Redundancy has been proposed as a prerequisite for objectivity, the defin…
