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…
Quantifying mixed-state entanglement via partial transpose and realignment moments
Poetri Sonya Tarabunga, Tobias Haug
Entanglement plays a crucial role in quantum information science and many-body physics, yet quantifying it in mixed quantum many-body systems has remained a notoriously difficult p…
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…
Bell sampling in Quantum Monte Carlo simulations
Poetri Sonya Tarabunga, Yi-Ming Ding
Quantum Monte Carlo (QMC) methods are essential for the numerical study of large-scale quantum many-body systems, yet their utility has been significantly hampered by the difficult…
Efficient witnessing and testing of magic in mixed quantum states
Tobias Haug, Poetri Sonya Tarabunga
Nonstabilizerness or `magic' is a crucial resource for quantum computers which can be distilled from noisy quantum states. However, determining the magic of mixed quantum has been…
Efficient mutual magic and magic capacity with matrix product states
Poetri Sonya Tarabunga, Tobias Haug
Stabilizer Rényi entropies (SREs) probe the non-stabilizerness (or magic) of many-body systems and quantum computers. Here, we introduce the mutual von-Neumann SRE and magic capaci…
