Quantum information
R Horodecki - ar** 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 …

Experimental optical simulator of reconfigurable and complex quantum environment
No quantum system can be considered totally isolated from its environment. In most cases
the interaction between the system of interest and the external degrees of freedom deeply …

Emergence of noncontextuality under quantum darwinism
Quantum Darwinism proposes that the proliferation of redundant information plays a major
role in the emergence of objectivity out of the quantum world. Is this kind of objectivity …

Quantum Darwinism in a composite system: Objectivity versus classicality
We investigate the implications of quantum Darwinism in a composite quantum system with
interacting constituents exhibiting a decoherence-free subspace. We consider a two-qubit …

Role of information backflow in the emergence of quantum Darwinism
Quantum Darwinism attempts to explain the emergence of objective reality of the state of a
quantum system in terms of redundant information about the system acquired by …

Quantum measurements and equilibration: the emergence of objective reality via entropy maximisation
Textbook quantum physics features two types of dynamics, reversible unitary dynamics and
irreversible measurements. The latter stands in conflict with the laws of thermodynamics and …

Quantum Darwinism-encoding transitions on expanding trees
B Ferté, X Cao - Physical Review A, 2024 - APS
Quantum Darwinism (QD) proposes that classical objectivity emerges from the broadcast of
information about a microscopic degree of freedom into multiple fractions of a many-body …
