- Abstract: The emergence of an objective classical picture is the core question of
quantum Darwinism. How does this reconstructed classical picture depends on the
resources available to observers? In this Letter, we develop an experimentally
relevant model of a qubit coupled dispersively to a transmission line and use
time-frequency signal processing techniques to understand if and how the
emergent classical picture is changed when we have the freedom to choose the
fragment decomposition and the type of radiation sent to probe the system. We
show the crucial role of correlations in the reconstruction procedure and point
to the importance of studying the type of measurements that must be done to
access an objective classical data.

Quantum correlations in four-wave-mixing from ensembles of cold two-level atoms may prevail without filtering over background light.
We detail the experimental procedure and the variation of the quantum correlation with various parameters of the system.
The non-classical aspects of the signal occur for short timescales, but the long timescales carry as well the classical correlations of the system.

In the description of this emerging behaviour finds its place the classical notion of time, as well as that of phase-space and trajectories on it.

By subjecting the auxiliary qubits to carefully tailored strong dissipations, we establish a one-to-one mapping between classical data and dissipative modes.
We train the dissipative central spin-qubit system to perform specific classification tasks akin to classical neural networks.

Inferring the parameters of a model based on experimental observations is central to the scientific method.
A particularly challenging setting is when the model is strongly indeterminate, i.e., when distinct sets of parameters yield identical observations.
We present a method for cracking such indeterminacy by exploiting additional information conveyed by an auxiliary set of observations sharing global parameters.
