Topological magic response in quantum spin chains
Ritu Nehra, Poetri Sonya Tarabunga, Martina Frau +3
Topological matter provides natural platforms for robust, non-local information storage, central to quantum error correction. Yet, while the relation between entanglement and topol…
Interplay of entanglement structures and stabilizer entropy in spin models
Michele Viscardi, Marcello Dalmonte, Alioscia Hamma +1
Understanding the interplay between nonstabilizerness and entanglement is crucial for uncovering the fundamental origins of quantum complexity. Recent studies have proposed entangl…
Robustness of Magic in the quantum Ising chain via Quantum Monte Carlo tomography
Hari Timsina, Yi-Ming Ding, Emanuele Tirrito +5
We study the behavior of magic as a bipartite correlation in the quantum Ising chain across its quantum phase transition, and at finite temperature. In order to quantify the magic…
Universal Spreading of Nonstabilizerness and Quantum Transport
Emanuele Tirrito, Poetri Sonya Tarabunga, Devendra Singh Bhakuni +3
We investigate how transport properties of -conserving dynamics impact the growth of quantum resources characterizing the complexity of many-body states. We quantify wave-fun…
Local vs non-local dynamics in cavity-coupled Rydberg atom arrays
Zeno Bacciconi, Hernan B. Xavier, Matteo Marinelli +2
Locality is a transversal principle that governs quantum dynamics of many-body systems. However, for cavity embedded systems, such fundamental notion is hindered by the presence of…
Nonstabilizerness in U(1) lattice gauge theory
Pedro R. Nicácio Falcão, Poetri Sonya Tarabunga, Martina Frau +3
We present a thorough investigation of nonstabilizerness - a fundamental quantum resource that quantifies state complexity within the framework of quantum computing - in a one-dime…
