The measures are reliable with respect to a “guessing” attack and depend on the end-to-end method of transfer of entropy from the chaotic physical system to the bit entrop...

]]>Perturbation theory is a crucial tool for many physical systems, when exact solutions are not available, or nonperturbative numerical solutions are intractable. Naive perturbation theory often fails on long timescales, leading to secularly growing solutions. These divergences have been treated with ...

The encoding of stochastic light intensity ($x$) into spikes is investigated in an experiment with retinas from bullfrogs to understand the mechanism of anticipation of a retina. Partial information deco...

In marine environments many factors play a role in determining the dynamics of a population, including the amount of nutrients, the temper...

In this work we present a simple but effective error mitigation technique based on the assumption that noise in a deep quantum circuit is well described by global depolarizing error channels. By measuring th...

]]>Globally coupled maps (GCMs) are prototypical examples of high-dimensional dynamical systems. Interestingly, GCMs formed by an ensemble of weakly coupled identical chaotic units generically exhibit a hyperchaotic “turbulent” state. A decade ago, Takeuchi *et al.* [Phys. Rev.
