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…
Quantum walks in two dimensions: controlling directional spreading with entangling coins and tunable disordered step operator
Caio B. Naves, Marcelo A. Pires, Diogo O. Soares-Pinto +1
We study a 2-D disordered time-discrete quantum walk based on 1-D `generalized elephant quantum walk' where an entangling coin operator is assumed and which paves the way to a new…
Exchange fluctuation theorems for strongly interacting quantum pumps
Akira Sone, Diogo O. Soares-Pinto, Sebastian Deffner
We derive a general quantum exchange fluctuation theorem for multipartite systems with arbitrary coupling strengths by taking into account the informational contribution of the bac…
Enhancing entanglement with the generalized elephant quantum walk from localized and delocalized states
Caio B. Naves, Marcelo A. Pires, Diogo O. Soares-Pinto +1
Recently, it was introduced a generalization of a nonstandard step operator named the elephant quantum walk (EQW). With proper statistical distribution for the steps, that generali…
