Generalized -body mean-field projections for classical simulation of -dimensional Heisenberg-picture dynamics
Federico Tomás B. Pérez, Gabriela Wójtowicz, Matthias Kost +1
Classical simulation of quantum many-body dynamics is challenged by the rapid growth of operator complexity, particularly in higher dimensions where tensor-network methods become i…
State-adapted generalized mean-field projections for Pauli propagation of Heisenberg dynamics
Federico Tomás B. Pérez, Gabriela Wójtowicz, Martin B. Plenio
The Heisenberg picture can make quantum many-body simulation efficient when evolved observables admit compact operator representation within low-dimensional structures. Conventiona…
Robustness of spin state superpositions for noisy quantum metrology
Trinidad B. Lantaño, Gabriela Wójtowicz, Susana F. Huelga +1
Quantum metrology faces major challenges in noisy environments, where decoherence rapidly degrades useful quantum resources. We investigate the dynamics of the precision limits giv…
Approaching the scaling limit of transport through lattices with dephasing
Subhajit Sarkar, Gabriela Wójtowicz, Bartłomiej Gardas +2
We examine the stationary--state equations for lattices with generalized Markovian dephasing and relaxation. When the Hamiltonian is quadratic, the single--particle correlation mat…
Quantum Fisher information from tensor network integration of Lyapunov equation
Gabriela Wójtowicz, Susana F. Huelga, Marek M. Rams +1
The Quantum Fisher Information (QFI) is a geometric measure of state deformation calculated along the trajectory parameterizing an ensemble of quantum states. It serves as a key co…
YASTN: Yet another symmetric tensor networks; A Python library for abelian symmetric tensor network calculations
Marek M. Rams, Gabriela Wójtowicz, Aritra Sinha +1
We present an open-source tensor network Python library for quantum many-body simulations. At its core is an abelian-symmetric tensor, implemented as a sparse block structure manag…
The confluence of fractured resonances at points of dynamical, many--body flare
Bitan De, Gabriela Wójtowicz, Marek M. Rams +2
Resonant transport occurs when there is a matching of frequencies across some spatial medium, increasing the efficiency of shuttling particles from one reservoir to another. We dem…
