Mereological Quantum Phase Transitions
Paolo Zanardi, Emanuel Dallas, Faidon Andreadakis
We introduce the novel concept of mereological quantum phase transition (m-QPTs). Our framework is based on a variational family of operator algebras defining generalized tensor pr…

Nonlocal Magic Generation and Information Scrambling in Noisy Clifford Circuits
Emanuel Dallas, Paolo Zanardi
In this work, we investigate the average information scrambling and nonlocal magic generation properties of random Clifford encoding-decoding circuits perturbed by local noise. We…

A Butterfly Effect in Encoding-Decoding Quantum Circuits
Emanuel Dallas, Faidon Andreadakis, Paolo Zanardi
The study of information scrambling has profoundly deepened our understanding of many-body quantum systems. Much recent research has been devote to understanding the interplay betw…
