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…
Higher-order Symmetric Quantum Mpemba Effect in Fragmented Systems
Sreemayee Aditya, Sara Murciano, Xhek Turkeshi
A quantum system can restore a broken symmetry faster the more strongly it initially breaks it, an anomaly known as the quantum Mpemba effect. Whether this effect survives once con…
Coherence dynamics in quantum many-body systems with conservation laws
Sreemayee Aditya, Emanuele Tirrito, Piotr Sierant +1
We study how conservation laws shape the spreading of quantum coherence in many-body dynamics. Focusing on -symmetric random circuits, charge-and-dipole conserving circuits,…
Assembling Extensive Quantum Fisher Information in Stabilizer Systems
Arnau Lira-Solanilla, Sreemayee Aditya, Xhek Turkeshi +1
We introduce a systematic framework to construct nonlocal observables with extensive quantum Fisher information (QFI) density in stabilizer codes. The construction maps stabilizer…
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…
