Anticoncentration and nonstabilizerness spreading under ergodic quantum dynamics
Emanuele Tirrito, Xhek Turkeshi, Piotr Sierant
Quantum state complexity metrics, such as anticoncentration and nonstabilizerness, or ``magic'', offer key insights into many-body physics, information scrambling, and quantum comp…
Anderson localization induced by structural disorder
Sourav Bhattacharjee, Piotr Sierant, Marek Dudyński +3
We examine the onset of Anderson localization in three-dimensional systems with structural disorder in the form of lattice irregularities and in the absence of any on-site disorder…
Many-body localization crossover is sharper in quasiperiodic spin chains
Pedro R. Nicácio Falcão, Adith Sai Aramthottil, Piotr Sierant +1
Due to a phenomenon of many-body localization (MBL), the strong disorder may significantly slow down or even completely hinder the thermalization of quantum many-body systems. A su…
Magic spreading in random quantum circuits
Xhek Turkeshi, Emanuele Tirrito, Piotr Sierant
Magic is the resource that quantifies the amount of beyond-Clifford operations necessary for universal quantum computing. It bounds the cost of classically simulating quantum syste…
Phenomenology of many-body localization in bond-disordered spin chains
Adith Sai Aramthottil, Piotr Sierant, Maciej Lewenstein +1
Many-body localization (MBL) hinders the thermalization of quantum many-body systems in the presence of strong disorder. In this work, we study the MBL regime in bond-disordered sp…
Quantum Algorithms for Inverse Participation Ratio Estimation in multi-qubit and multi-qudit systems
Yingjian Liu, Piotr Sierant, Paolo Stornati +2
Inverse Participation Ratios (IPRs) and the related Participation Entropies quantify the spread of a quantum state over a selected basis of the Hilbert space, offering insights int…
