Integrability and Chaos via fractal analysis of Spectral Form Factors: Gaussian approximations and exact results
Lorenzo Campos Venuti, Jovan Odavić, Alioscia Hamma
It is well known that the spectral form factor (SFF) of a possibly degenerate many-body Hamiltonian can be identified with a planar random walk taking steps of unequal length. In t…
Non-stabilizerness and violations of CHSH inequalities
Stefano Cusumano, Lorenzo Campos Venuti, Simone Cepollaro +7
We study quantitatively the interplay between entanglement and non-stabilizer resources in violating the CHSH inequalities. We show that, while non-stabilizer resources are necessa…
Entanglement and Stabilizer entropies of random bipartite pure quantum states
Daniele Iannotti, Gianluca Esposito, Lorenzo Campos Venuti +1
The interplay between non-stabilizerness and entanglement in random states is a very rich arena of study for the understanding of quantum advantage and complexity. In this work, we…
Optimal Control for Closed and Open System Quantum Optimization
Lorenzo Campos Venuti, Domenico D'Alessandro, Daniel A. Lidar
We provide a rigorous analysis of the quantum optimal control problem in the setting of a linear combination of two noncommuting Hamiltonians and . This in…
Topological Protection of Coherence in Noisy Open Quantum Systems
Yu Yao, Henning Schlömer, Zhengzhi Ma +2
We consider topological protection mechanisms in dissipative quantum systems in the presence of quenched disorder, with the intent to prolong coherence times of qubits. The physica…
Quantum coherence and the localization transition
Georgios Styliaris, Namit Anand, Lorenzo Campos Venuti +1
A dynamical signature of localization in quantum systems is the absence of transport which is governed by the amount of coherence that configuration space states possess with respe…
