Magic of Kitaev spin liquids
Eleonora Lamma, Tim Bauer, Marcello Dalmonte +1
Quantum spin liquids (QSLs) are long-range entangled phases of matter and a natural setting for exploring how quantum correlations generate quantum complexity. Motivated by the eme…
Nonlocal nonstabilizerness in free fermion models
Mario Collura, Benjamin Béri, Emanuele Tirrito
Nonlocal magic quantifies the irreducible nonstabilizerness of a bipartite quantum state after optimizing over local basis changes. We study nonlocal magic for pure fermionic Gauss…
Complexity of Quantum Trajectories
Luca Lumia, Emanuele Tirrito, Mario Collura +2
Open quantum systems can be described by unraveling Lindblad master equations into ensembles of quantum trajectories. Here we investigate how the complexity of such trajectories is…
Operator delocalization in disordered spin chains via exact MPO marginals
Jonnathan Pineda, Mario Collura, Gianluca Passarelli +3
We investigate operator delocalization in disordered one-dimensional spin chains by introducing -- besides the already known operator mass -- a complementary measure of operator co…
