Noise mitigation of quantum observables via learning from Hamiltonian symmetry decays
Javier Oliva del Moral, Olatz Sanz Larrarte, Joana Fraxanet +2
We present a new quantum error mitigation technique (QEM), called GUiding Extrapolations from Symmetry decayS (GUESS), which exploits Hamiltonian symmetries to improve accuracy of…
Variational Quantum Eigensolver for Real-World Finance: Scalable Solutions for Dynamic Portfolio Optimization Problems
Irene De León, Danel Arias, Manuel Martín-Cordero +9
We present a scalable, hardware-aware methodology for extending the Variational Quantum Eigensolver (VQE) to large, realistic Dynamic Portfolio Optimization (DPO) problems. Buildin…
Real-Time Dynamics in a (2+1)-D Gauge Theory: The Stringy Nature on a Superconducting Quantum Simulator
Jesús Cobos, Joana Fraxanet, César Benito +7
Understanding the confinement mechanism in gauge theories and the universality of effective string-like descriptions of gauge flux tubes remains a fundamental challenge in modern p…
Geometrical frustration, power law tunneling and non-local gauge fields from scattered light
Pavel P. Popov, Joana Fraxanet, Luca Barbiero +1
Designing the amplitude and range of couplings in quantum systems is a fundamental tool for exploring a large variety of quantum mechanical effects. Here, we consider off-resonant…
Topological properties of the long-range Kitaev chain with Aubry-André-Harper modulation
Joana Fraxanet, Utso Bhattacharya, Tobias Grass +3
We present a detailed study of the topological properties of the Kitaev chain with long-range pairing terms and in the presence of an Aubry-André-Harper on-site potential. Specific…
