Nonlocal Magic Spreading in Many-body Quantum Dynamics: From Chaotic Evolution to Quasi-particle Picture in Integrable Models
Sreemayee Aditya, Piotr Sierant, Xhek Turkeshi
Entanglement and magic are resources that reveal complementary aspects of quantum many-body systems. Their interplay is captured by nonlocal magic, the magic that survives arbitrar…
Pauli spectrum and nonstabilizerness of random fermionic Gaussian states
Xhek Turkeshi, Piotr Sierant, Poetri Sonya Tarabunga
We characterize the magic of random fermionic Gaussian states through their Pauli spectrum and their stabilizer entropies. For the Haar ensemble of Majorana Gaussian states we deri…
Restricted typicality in non-equilibrium quantum many-body systems
Konrad Pawlik, Piotr Sierant, Jakub Zakrzewski
Characterizing the time evolution of generic quantum many-body systems is a fundamental challenge, as representing the exact state requires exponentially scaling computational reso…
Williamson majorization theory of fermionic non-Gaussianity
Xhek Turkeshi, Piotr Sierant, Poetri Sonya Tarabunga
Pure-state entanglement rests on a single algebraic backbone: majorization of the Schmidt spectrum governs state conversion under local operations and classical communication, and…
Equivalence of quantum resources under ergodic dynamics
Sreemayee Aditya, Xhek Turkeshi, Piotr Sierant
Quantum resource theories characterize distinct forms of nonclassicality in many-body quantum states, raising the question of whether these resources evolve independently under gen…
Unitary Designs from Doped Matchgate Circuits
Fabian Ballar Trigueros, Zheng-Hang Sun, Xhek Turkeshi +2
Matchgate circuits realize free-fermion dynamics: they are efficiently classically simulable, yet cannot on their own generate the generic randomness required for universal computa…
