Decoherence from a chaotic environment: An upside-down “oscillator” as a model

Decoherence from a chaotic environment: An upside-down “oscillator” as a model

Chaotic evolutions exhibit exponential sensitivity to initial conditions. This suggests that even very small perturbations resulting from weak coupling of a quantum chaotic environment to the position of a system whose state is a non-local superposition will lead to rapid decoherence. However, it is also known that quantum counterparts of …
