Noise-induced classical phases in optimally-unraveled random quantum circuits
Lorenzo Fioroni, Filippo Ferrari, Emanuele Tirrito
We study the classical simulability of open quantum dynamics using random Clifford circuits doped with non-Clifford phase rotations and subject to local noise. We unravel the dynam…
Global and nonlocal magic of quantum many-body scars
Lukas Ebner, Giovanni Cataldi, Kaidi Xu +2
Nonergodic features of chaotic quantum many-body systems are commonly characterized through local observables, fidelity, and entanglement entropy. Here, using global and nonlocal m…
Quantum Resources in Disorder-Free Localization Dynamics of Gauge Theories
Devendra Singh Bhakuni, Giovanni Cataldi, Jad C. Halimeh +1
Quantum-state complexity diagnostics provide valuable insight into many-body dynamics, information scrambling, and quantum computation. Here, we investigate the real-time dynamics…
The true cost of factoring: Linking magic and number-theoretic complexity in Shor's algorithm
Alessio Paviglianiti, Matteo Seclì, Emanuele Tirrito +1
The execution cost of quantum algorithms is typically quantified through asymptotic gate counts and qubit register sizes, yet these metrics do not directly capture which genuinely…
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…
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,…
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…
