The non-stabilizerness of fermionic Gaussian states
Mario Collura, Jacopo De Nardis, Vincenzo Alba +1
We introduce an efficient method to quantify nonstabilizerness in fermionic Gaussian states, overcoming the long-standing challenge posed by their extensive entanglement. Using a p…
Accuracy of time-dependent GGE under weak dissipation
Luca Lumia, Gianni Aupetit-Diallo, Jérôme Dubail +1
Unitary integrable models typically relax to a stationary Generalized Gibbs Ensemble (GGE), but in experimental realizations dissipation often breaks integrability. In this work, w…
Stabilizer disentangling of conformal field theories
Martina Frau, Poetri Sonya Tarabunga, Mario Collura +2
Understanding how entanglement can be reduced through simple operations is crucial for both classical and quantum algorithms. We investigate the entanglement properties of lattice…
Semiclassical Quantum Trajectories in the Monitored Lipkin-Meshkov-Glick Model
Alessandro Santini, Luca Lumia, Mario Collura +1
Monitored quantum system have sparked great interest in recent years due to the possibility of observing measurement-induced phase transitions (MIPTs) in the full-counting statisti…
Thermalization propagation front and robustness against avalanches in localized systems
Annarita Scocco, Gianluca Passarelli, Mario Collura +2
We investigate the robustness of the many-body localized (MBL) phase to the quantum-avalanche instability by studying the dynamics of a localized spin chain coupled to a …
Clifford Dressed Time-Dependent Variational Principle
Antonio Francesco Mello, Alessandro Santini, Guglielmo Lami +2
We propose an enhanced Time-Dependent Variational Principle (TDVP) algorithm for Matrix Product States (MPS) that integrates Clifford disentangling techniques to efficiently manage…
Variational ground-state quantum adiabatic theorem
Bojan Žunkovič, Pietro Torta, Giovanni Pecci +2
We present a variational quantum adiabatic theorem, which states that, under certain assumptions, the adiabatic dynamics projected onto a variational manifold follow the instantane…
Hybrid Stabilizer Matrix Product Operator
Antonio Francesco Mello, Alessandro Santini, Mario Collura
We introduce a novel hybrid approach combining tensor network methods with the stabilizer formalism to address the challenges of simulating many-body quantum systems. By integratin…
Estimating Non-Stabilizerness Dynamics Without Simulating It
Alessio Paviglianiti, Guglielmo Lami, Mario Collura +1
We introduce the Iterative Clifford Circuit Renormalization (ICCR), a novel technique designed to efficiently handle the dynamics of non-stabilizerness (a.k.a. quantum magic) in ge…
Non-stabilizerness versus entanglement in matrix product states
M. Frau, P. S. Tarabunga, M. Collura +2
In this paper, we investigate the relationship between entanglement and non-stabilizerness (also known as magic) in matrix product states (MPSs). We study the relation between magi…
Retrieving non-stabilizerness with Neural Networks
Antonio Francesco Mello, Guglielmo Lami, Mario Collura
Quantum computing's promise lies in its intrinsic complexity, with entanglement initially heralded as its hallmark. However, the quest for quantum advantage extends beyond entangle…
Learning the stabilizer group of a Matrix Product State
Guglielmo Lami, Mario Collura
We present a novel classical algorithm designed to learn the stabilizer group -- namely the group of Pauli strings for which a state is a eigenvector -- of a given Matrix P…
