Topological magic response in quantum spin chains
Ritu Nehra, Poetri Sonya Tarabunga, Martina Frau +3
Topological matter provides natural platforms for robust, non-local information storage, central to quantum error correction. Yet, while the relation between entanglement and topol…
Magic of the Well: assessing quantum resources of fluid dynamics data
Antonio Francesco Mello, Mario Collura, E. Miles Stoudenmire +1
We investigate the quantum resource requirements of a dataset generated from simulations of two-dimensional, periodic, incompressible shear flow, aimed at training machine learning…
Quantum complexity across thermal phase transition in the transverse field Ising chain with long-range couplings
Meghadeepa Adhikary, Nishan Ranabhat, Mario Collura
We investigate the behavior of the Schmidt gap, the von Neumann entanglement entropy, and the non-stabiliserness in proximity to the classical phase transition of the one-dimension…
Robustness of Magic in the quantum Ising chain via Quantum Monte Carlo tomography
Hari Timsina, Yi-Ming Ding, Emanuele Tirrito +5
We study the behavior of magic as a bipartite correlation in the quantum Ising chain across its quantum phase transition, and at finite temperature. In order to quantify the magic…
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…
Rise and fall of nonstabilizerness via random measurements
Annarita Scocco, Wai-Keong Mok, Leandro Aolita +2
We investigate the dynamics of nonstabilizerness - also known as `magic' - in monitored quantum circuits composed of random Clifford unitaries and local projective measurements. Fo…
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…
Clifford-Dressed Variational Principles for Precise Loschmidt Echoes
Antonio Francesco Mello, Alessandro Santini, Mario Collura
We extend the recently introduced Clifford dressed Time-Dependent Variational Principle (TDVP) to efficiently compute many-body wavefunction amplitudes in the computational basis.…
Non-stabilizerness of Neural Quantum States
Alessandro Sinibaldi, Antonio Francesco Mello, Mario Collura +1
We introduce a methodology to estimate non-stabilizerness or "magic", a key resource for quantum complexity, with Neural Quantum States (NQS). Our framework relies on two schemes b…
