Quantum scrambling of algebras of observables: the -symmetric case
Paolo Zanardi, J. Karson Lewis
We consider unitary quantum scrambling for an entire class of observable algebras whose commutant is generated by a Hermitian in…
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…
Tensor Product Structure Geometry under Unitary Channels
Faidon Andreadakis, Paolo Zanardi
In quantum many-body systems, complex dynamics delocalize the physical degrees of freedom. This spreading of information throughout the system has been extensively studied in relat…
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…
Operator Space Entangling Power of Quantum Dynamics and Local Operator Entanglement Growth in Dual-Unitary Circuits
Faidon Andreadakis, Emanuel Dallas, Paolo Zanardi
Operator entanglement is a well-established measure of operator complexity across a system bipartition. In this work, we introduce a measure for the ability of a unitary channel to…
Long-time Quantum Scrambling and Generalized Tensor Product Structures
Faidon Andreadakis, Emanuel Dallas, Paolo Zanardi
Much recent work has been devoted to the study of information scrambling in quantum systems. In this paper, we study the long-time properties of the algebraic out-of-time-order-cor…
Mutual averaged non-commutativity of quantum operator algebras
Paolo Zanardi
We introduce an elementary measure of non-commutativity between two algebras of quantum operators acting on the same Hilbert space. This quantity, which we call Mutual Averaged Non…
