Utility-scale quantum experiments using dynamic circuits to address collective dissipation in interacting qubits
Benjamin Tirado, Joana Fraxanet, Adrián Juan-Delgado +2
Open quantum systems are central to quantum optics, condensed matter, and chemistry, yet their simulation remains challenging for both classical and near-term quantum hardware. In…
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…

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…
Flux Magnetism in a Strongly Interacting Dipolar Lattice Supersolid under Tunable Gauge Fields
Michele Miotto, Pietro Lombardi, Giovanni Ferioli +4
Supersolidity and magnetism are fundamental phenomena characterizing strongly correlated matter. Here we unveil a mechanism that directly connects these two regimes and can be expe…
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…
Higher-order topological Peierls insulator in a two-dimensional atom-cavity system
Joana Fraxanet, Alexandre Dauphin, Maciej Lewenstein +2
In this work, we investigate a two-dimensional system of ultracold bosonic atoms inside an optical cavity, and show how photon-mediated interactions give rise to a plaquette-ordere…
A hybrid quantum algorithm to detect conical intersections
Emiel Koridon, Joana Fraxanet, Alexandre Dauphin +3
Conical intersections are topologically protected crossings between the potential energy surfaces of a molecular Hamiltonian, known to play an important role in chemical processes…
The Coming Decades of Quantum Simulation
Joana Fraxanet, Tymoteusz Salamon, Maciej Lewenstein
Contemporary quantum technologies face major difficulties in fault tolerant quantum computing with error correction, and focus instead on various shades of quantum simulation (Nois…
