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 …

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 …

Decoherence without entanglement and quantum Darwinism
It is often assumed that decoherence arises as a result of the entangling interaction between
a quantum system and its environment, as a consequence of which the environment …

Limits on quantum measurement engines
A quantum measurement involves energy exchanges between the system to be measured
and the measuring apparatus. Some of them involve energy losses, for example because …

Time and classical equations of motion from quantum entanglement via the Page and Wootters mechanism with generalized coherent states
We draw a picture of physical systems that allows us to recognize what “time” is by requiring
consistency with the way that time enters the fundamental laws of Physics. Elements of the …

Threshold size for the emergence of classical-like behavior
In this work we design a procedure to estimate the minimum size beyond which a system is
amenable to a classical-like description, ie, a description based on representative points in …

Emergent classicality in general multipartite states and channels
In a quantum measurement process, classical information about the measured system
spreads throughout the environment. Meanwhile, quantum information about the system …

Multiclass classification of dephasing channels
We address the use of neural networks (NNs) in classifying the environmental parameters of
single-qubit dephasing channels. In particular, we investigate the performance of linear …

Premeasurement reliability and accessibility of quantum measurement apparatuses
We propose a characterization of measurement apparatuses based on their
premeasurement reliability and accessibility. Our notion of premeasurement reliability …

From a quantum theory to a classical one
We present and discuss a formal approach for describing the quantum to classical crossover
based on the group-theoretic construction of generalized coherent states. The method was …
