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…
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.…
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…
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…
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…
