Robustness of Quantum Signal Processing and Resource-aware Polynomial Design
Thiago O. Maciel, Giancarlo Camilo, Allan Tosta +3
Quantum signal processing (QSP) realizes operator functions through polynomial transformations of a finite degree. In addition to function approximation errors, realistic implement…
Compilation-informed probabilistic logical-error cancellation
Giancarlo Camilo, Thiago O. Maciel, Allan Tosta +4
The potential of quantum computers to outperform classical ones in practically useful tasks remains challenging in the near term due to scaling limitations and high error rates of…
Quantum optimization with exact geodesic transport
André J. Ferreira-Martins, Renato M. S. Farias, Giancarlo Camilo +6
We introduce an architecture for variational quantum algorithms that can be efficiently trained via parameter updates along exact geodesics on the Riemannian state manifold. This f…
Randomized semi-quantum matrix processing
Allan Tosta, Thais de Lima Silva, Giancarlo Camilo +1
We present a hybrid quantum-classical framework for simulating generic matrix functions more amenable to early fault-tolerant quantum hardware than standard quantum singular-value…
Fermionic anyons: entanglement and quantum computation from a resource-theoretic perspective
Allan Tosta, Antônio C. Lourenço, Daniel Brod +2
Quantum computational models can be approached via the lens of resources needed to perform computational tasks, where a computational advantage is achieved by consuming specific fo…
Grand Unification of continuous-variable codes
Allan D. C. Tosta, Thiago O. Maciel, Leandro Aolita
Quantum error correction codes in continuous variables (also called CV codes, or single-mode bosonic codes) have recently been identified to be a technologically viable option for…
Gaussian optical networks for one-dimensional anyons
Allan D. C. Tosta, Ernesto F. Galvão, Daniel J. Brod
We study the dynamics of bosonic and fermionic anyons defined on a one-dimensional lattice, under the effect of Hamiltonians quadratic in creation and annihilation operators, also…
Quantum computation from fermionic anyons on a 1D lattice
Allan D. C. Tosta, Daniel J. Brod, Ernesto F. Galvão
Fermionic linear optics corresponds to the dynamics of free fermions, and is known to be efficiently simulable classically. We define fermionic anyon models by deforming the fermio…
