[HTML][HTML] Quantum information scrambling in adiabatically driven critical systems

R Puebla, FJ Gómez-Ruiz - Entropy, 2024 - pmc.ncbi.nlm.nih.gov
Quantum information scrambling refers to the spread of the initially stored information over
many degrees of freedom of a quantum many-body system. Information scrambling is …

An operational definition of quantum information scrambling

GL Monaco, L Innocenti, D Cilluffo… - Quantum Science …, 2024 - iopscience.iop.org
Quantum information scrambling (QIS) is a characteristic feature of several quantum
systems, ranging from black holes to quantum communication networks. While accurately …

More on the upper bound of holographic n-partite information

XX Ju, WB Pan, YW Sun, YT Wang, Y Zhao - arxiv preprint arxiv …, 2024 - arxiv.org
We show that there exists a huge amount of multipartite entanglement in holography by
studying the upper bound for holographic $ n $-partite information $ I_n $ that $ n-1$ fixed …

Information Scrambling in Bosonic Gaussian Dynamics

A Mollabashi, S Rahimi-Keshari - arxiv preprint arxiv:2408.12089, 2024 - arxiv.org
We show that randomness in quadratic bosonic Hamiltonians results in certain information
scrambling diagnostics, mirroring those in chaotic systems. Specifically, for initial Gaussian …

Non-stabilizerness and entanglement from cat-state injection

FCR Peres, R Wagner, EF Galvão - New Journal of Physics, 2024 - iopscience.iop.org
Recently, cat states have been used to heuristically improve the runtime of a classical
simulator of quantum circuits based on the diagrammatic ZX-calculus. Here we investigate …
