Role of spectral structure in adiabatic ground-state preparation of the XXZ model

Francisco Albarrán-Arriagada, Juan Carlos Retamal

Adiabatic ground-state preparation is fundamentally limited by the spectral structure of the time-dependent Hamiltonian, particularly by gap reductions and degeneracies that induce…

Quantum Approximate Optimization Algorithm with Fixed Number of Parameters

Sebastián Saavedra-Pino, Ricardo Quispe-Mendizábal, Gabriel Alvarado Barrios +3

We introduce a novel quantum optimization paradigm: the Fixed-Parameter-Count Quantum Approximate Optimization Algorithm (FPC-QAOA). It is a scalable variational framework that mai…

Equally entangled multiqubit states

Francisco Albarrán-Arriagada, Guillermo Romero, Juan Carlos Retamal

We present a protocol for generating multiqubit quantum states with translationally invariant pairwise entanglement. Our approach is tailored for digital quantum computers with res…

Resilient superconducting-element design with genetic algorithms

F. A. Cárdenas-López, J. C. Retamal, Xi Chen +2

We present superconducting quantum circuits which exhibit atomic energy spectrum and selection rules as ladder and lambda three-level configurations designed by means of genetic al…
