Growth and spreading of quantum resources under random circuit dynamics
Sreemayee Aditya, Xhek Turkeshi, Piotr Sierant
Quantum many-body dynamics generate nonclassical correlations naturally described by quantum resource theories. Quantum magic resources (or nonstabilizerness) capture deviation fro…
Mpemba Effects in Quantum Complexity
Sreemayee Aditya, Alessandro Summer, Piotr Sierant +1
The Mpemba effect is the phenomenon whereby systems farther from equilibrium may relax faster. In this work, we show that this counterintuitive behavior appears in the very measure…
Non-stabilizerness in quantum-enhanced metrological protocols
Tanausú Hernández-Yanes, Piotr Sierant, Jakub Zakrzewski +1
Non-stabilizerness (colloquially "magic") characterizes genuinely quantum (beyond-Clifford) operations necessary for preparation of quantum states, and can be measured by stabilize…
Many-body delocalization with a two-dimensional 70-qubit superconducting quantum simulator
Tian-Ming Li, Zheng-Hang Sun, Yun-Hao Shi +35
Quantum many-body systems with sufficiently strong disorder can exhibit a non-equilibrium phenomenon, known as the many-body localization (MBL), which is distinct from conventional…
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…
Fermionic Magic Resources of Quantum Many-Body Systems
Piotr Sierant, Paolo Stornati, Xhek Turkeshi
Understanding the computational complexity of quantum states is a central challenge in quantum many-body physics. In qubit systems, fermionic Gaussian states can be efficiently sim…
