Fidelity-based distance bounds for -qubit approximate quantum error correction
Guilherme Fiusa, Diogo O. Soares-Pinto, Diego Paiva Pires
The Eastin-Knill theorem is a central result of quantum error correction theory and states that a quantum code cannot correct errors exactly, possess continuous symmetries, and imp…

Mixedness timescale in non-Hermitian quantum systems
Diego Paiva Pires, Tommaso Macrì
We discuss the short-time perturbative expansion of the linear entropy for finite-dimensional quantum systems whose dynamics can be effectively described by a non-Hermitian Hamilto…

Unified entropies and quantum speed limits for nonunitary dynamics
Diego Paiva Pires
We discuss a class of quantum speed limits (QSLs) based on unified quantum ()-entropy for nonunitary physical processes. The bounds depend on both the Schatten speed and the s…
