Quantum theory of the classical: Einselection, envariance, quantum darwinism and extantons
WH Zurek - Entropy, 2022 - mdpi.com
Core quantum postulates including the superposition principle and the unitarity of evolutions
are natural and strikingly simple. I show that—when supplemented with a limited version of …

Eavesdropping on the decohering environment: Quantum darwinism, amplification, and the origin of objective classical reality
“How much information about a system S can one extract from a fragment F of the
environment E that decohered it?” is the central question of Quantum Darwinism. To date …

Redundantly amplified information suppresses quantum correlations in many-body systems
We establish bounds on quantum correlations in many-body systems. They reveal what sort
of information about a quantum system can be simultaneously recorded in different parts of …

Observing Schrödinger's cat with artificial intelligence: emergent classicality from information bottleneck
Z Zhang, YZ You - Machine Learning: Science and Technology, 2024 - iopscience.iop.org
We train a generative language model on the randomized local measurement data collected
from Schrödinger's cat quantum state. We demonstrate that the classical reality emerges in …

One dimensional gapped quantum phases and enriched fusion categories
A bstract In this work, we use Ising chain and Kitaev chain to check the validity of an earlier
proposal in arXiv: 2011.02859 that enriched fusion (higher) categories provide a unified …

Bootstrap embedding on a quantum computer
We extend molecular bootstrap embedding to make it appropriate for implementation on a
quantum computer. This enables solution of the electronic structure problem of a large …

Jordan products of quantum channels and their compatibility
Given two quantum channels, we examine the task of determining whether they are
compatible—meaning that one can perform both channels simultaneously but, in the future …

Branching states as the emergent structure of a quantum universe
Quantum Darwinism builds on decoherence theory to explain the emergence of classical
behavior in a fundamentally quantum universe. Within this framework we prove two crucial …

Device-independent witness for the nonobjectivity of quantum dynamics
Quantum Darwinism offers an explanation for the emergence of classical objective features
(those we are used to at macroscopic scales) from quantum properties at the microscopic …
