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…

An Exact Link between Nonlocal Nonstabilizerness and Operator Entanglement
Faidon Andreadakis, Paolo Zanardi
Nonstabilizerness is a quantum property of states associated with the non-Clifford resources required for their preparation. As a resource, nonstabilizerness complements entangleme…
