Random ensembles of symplectic and unitary states are indistinguishable
Maxwell West, Antonio Anna Mele, Martin Larocca +1
A unitary state -design is an ensemble of pure quantum states whose moments match up to the -th order those of states uniformly sampled from a -dimensional Hilbert space.…
Loschmidt echo approach to Krylov-subspace approximation error estimation
Julian Ruffinelli, Emiliano Fortes, Martín Larocca +1
The Krylov subspace method is a standard approach to approximate quantum evolution, allowing to treat systems with large Hilbert spaces. Although its application is general, and su…
K-GRAPE: A Krylov Subspace approach for the efficient control of quantum many-body dynamics
Martin Larocca, Diego Wisniacki
The Gradient Ascent Pulse Engineering (GRAPE) is a celebrated control algorithm with excellent converging rates, owing to a piece-wise-constant ansatz for the control function that…
Quantum metrology in a non-Markovian quantum evolution
Nicolás Mirkin, Martin Larocca, Diego Wisniacki
The problem of quantum metrology under the context of a particular non-Markovian quantum evolution is explored. We study the dynamics of the quantum Fisher information (QFI) of a c…
Navigating on Quantum Control Solution Subspaces
Martin Larocca, Esteban A. Calzetta, Diego A. Wisniacki
Quantum Optimal Control (QOC) is the field devoted to the production of external control protocols that actively guide quantum dynamics. Solutions to QOC problems were shown to con…
Exploiting Landscape Geometry to Enhance Quantum Optimal Control
Martin Larocca, Esteban A. Calzetta, Diego A. Wisniacki
The successful application of Quantum Optimal Control (QOC) over the past decades unlocked the possibility of directing the dynamics of quantum systems. Nevertheless, solutions obt…
