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…
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…
Emergence of Generic Entanglement Structure in Doped Matchgate Circuits
Alessio Paviglianiti, Luca Lumia, Emanuele Tirrito +4
Free fermionic Gaussian, a.k.a. matchgate, random circuits exhibit atypical behavior compared to generic interacting systems. They produce anomalously slow entanglement growth, cha…
Magic phase transitions in monitored gaussian fermions
Emanuele Tirrito, Luca Lumia, Alessio Paviglianiti +4
Monitored quantum systems, where unitary dynamics compete with continuous measurements, exhibit dynamical transitions as the measurement rate is varied. These reflect abrupt change…
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…
Role of Nonstabilizerness in Quantum Optimization
Chiara Capecci, Gopal Chandra Santra, Alberto Bottarelli +2
Quantum optimization has emerged as a promising approach for tackling complicated classical optimization problems using quantum devices. However, the extent to which such algorithm…
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…
Nonstabilizerness dynamics in many-body localized systems
Pedro R. Nicácio Falcão, Piotr Sierant, Jakub Zakrzewski +1
Nonstabilizerness, also known as ``magic'', quantifies the deviation of quantum states from stabilizer states, capturing the complexity necessary for quantum computational advantag…
