Quantum algorithms for the exponentiation of Toeplitz matrices and applications in partial differential equations
Xabier Gutiérrez, Nicola Mariella, Javier González-Conde +2
We present quantum algorithms to approximate the exponential of banded Toeplitz matrices. These matrices have central importance in many PDE related problems, but their quantum imp…
Quantum Eigenvalue Transformations for Arbitrary Matrices
Xabier Gutiérrez, Lorenzo Laneve, Mikel Sanz
Quantum Signal Processing (QSP) and Quantum Singular Value Transformation (QSVT) provide an efficient framework for implementing polynomials of block-encoded matrices, and thus off…
Digital-Analog Quantum Computing with Qudits
Alatz Alvarez-Ahedo, Mikel Garcia de Andoin, Mikel Sanz
Digital-analog quantum computing with two-level systems is a computational paradigm that combines an analog Hamiltonian with single-qubit gates to achieve universality. We extend t…
Tight bound for the total time in digital-analog quantum computation
Mikel Garcia-de-Andoin, Mikel Sanz
Digital-analog quantum computing (DAQC) is a universal computational paradigm that combines the evolution under an entangling Hamiltonian with the application of single-qubit gates…
Impact and mitigation of Hamiltonian characterization errors in digital-analog quantum computation
Mikel Garcia-de-Andoin, Alatz Álvarez-Ahedo, Adrián Franco-Rubio +1
Digital-analog is a universal quantum computing paradigm which employs the natural entangling Hamiltonian of the system and single-qubit gates as resources. Here, we study the stab…
Symmetry-enhanced Counterdiabatic Quantum Algorithm for Qudits
Alberto Bottarelli, Mikel Garcia de Andoin, Pranav Chandarana +4
Qubit-based variational quantum algorithms have undergone rapid development in recent years but still face several challenges. In this context, we propose a symmetry-enhanced digit…
Formulation of the Electric Vehicle Charging and Routing Problem for a Hybrid Quantum-Classical Search Space Reduction Heuristic
M. Garcia de Andoin, A. Bottarelli, S. Schmitt +3
Combinatorial optimization problems have attracted much interest in the quantum computing community in the recent years as a potential testbed to showcase quantum advantage. In thi…
