Quantum State Designs via Magic Teleportation
Hugo Lóio, Guglielmo Lami, Lorenzo Leone +3
We investigate how non-stabilizer resources enable the emergence of quantum state designs within the projected ensemble. Starting from initial states with finite magic and applying…
Universality in the Anticoncentration of Noisy Quantum Circuits at Finite Depths
Arman Sauliere, Guglielmo Lami, Corentin Boyer +2
We present universal properties of anticoncentration in weakly noisy quantum circuits at finite depth. We develop a generic framework for single- and multi-qubit noise channels in…
Emergence of Generic Entanglement Structure in Doped Matchgate Circuits
Alessio Paviglianiti, Luca Lumia, Emanuele Tirrito +4
Free fermionic Gaussian, a.k.a. matchgate, random circuits exhibit atypical behavior compared to generic interacting systems. They produce anomalously slow entanglement growth, cha…
Magic phase transitions in monitored gaussian fermions
Emanuele Tirrito, Luca Lumia, Alessio Paviglianiti +4
Monitored quantum systems, where unitary dynamics compete with continuous measurements, exhibit dynamical transitions as the measurement rate is varied. These reflect abrupt change…
Overcoming the entanglement barrier with sampled tensor networks
Stefano Carignano, Guglielmo Lami, Jacopo De Nardis +1
The rapid growth of entanglement under unitary time evolution is the primary bottleneck for modern tensor-network techniques--such as Matrix Product States (MPS)--when computing ti…
Quantum State Design and Emergent Confinement Mechanism in Measured Tensor Network States
Guglielmo Lami, Andrea De Luca, Xhek Turkeshi +1
Randomness is a fundamental aspect of quantum mechanics, arising from the measurement process that collapses superpositions into definite outcomes according to Born's rule. Generat…
Tensor Network Techniques for Quantum Computation
Mario Collura, Guglielmo Lami, Nishan Ranabhat +1
This book serves as an introductory yet thorough guide to tensor networks and their applications in quantum computation and quantum information, designed for advanced undergraduate…
Beginner's Lecture Notes on Quantum Spin Chains, Exact Diagonalization and Tensor Networks
Guglielmo Lami, Mario Collura, Nishan Ranabhat
Aimed at introducing readers to the physics of strongly correlated many-body systems, these notes focus on numerical methods, with detailed discussions on implementing working code…
Universality in the Anticoncentration of Chaotic Quantum Circuits
Arman Sauliere, Beatrice Magni, Guglielmo Lami +2
We identify a \emph{universal functional form} that governs anticoncentration in random quantum circuits-one that holds across diverse circuit architectures and depths, and crucial…
Correlations, Spectra and Entanglement Transitions in Ensembles of Matrix Product States
Hugo Lóio, Guillaume Cecile, Sarang Gopalakrishnan +2
We investigate ensembles of Matrix Product States (MPSs) generated by quantum circuit evolution followed by projection onto MPSs with a fixed bond dimension . Specifically, we c…
