# (Anti-)Zeno-based dynamical control of the unfolding of quantum Darwinism

## TL;DR

This paper explores how the quantum Zeno and anti-Zeno effects can be used to control the rate of information encoding in quantum Darwinism, aiding experimental investigation of its phenomena.

## Contribution

It introduces a method to manipulate the temporal unfolding of quantum Darwinism using the quantum (anti-)Zeno effect, enabling tailored control of decoherence rates.

## Key findings

- Control of information encoding rate via Zeno effects
- Enhanced or suppressed decoherence in quantum systems
- Potential for improved quantum Darwinism experiments

## Abstract

We combine the collisional picture for open system dynamics and the control of the rate of decoherence provided by the quantum (anti-)Zeno effect to illustrate the temporal unfolding of the redundant encoding of information into a multipartite environment that is at the basis of Quantum Darwinism, and to control it. The rate at which such encoding occurs can be enhanced or suppressed by tuning the dynamical conditions of system-environment interaction in a suitable and remarkably simple manner. This would help the design of a new generation of quantum experiments addressing the elusive phenomenology of Quantum Darwinism and thus its characterization.
