This repository provides data related to the work: "Digital-Analog Quantum Computing (DAQC) of fermion-boson models in superconducting circuits", including both ideal and noisy simulations.
We present a digital-analog quantum algorithm designed to simulate the Hubbard-Holstein model natively in superconducting quantum devices, which describes strongly correlated fermion-boson interactions. This simulation is implemented within a suitable superconducting circuit architecture making use of a linear chain of qubits coupled via resonators to emulate fermion tunneling and fermion-boson interactions.
As an example, we demonstrate the quantum simulation of a half-filled two-site Hubbard-Holstein model. The results show time-dependent state fidelities exceeding 0.98, confirming the feasibility of our approach for studying the dynamical behavior of solid-state systems.
This repository includes the following components:
- data – Contains the raw data from simulations.
- draft_figs_repo.py – Jupyter notebooks for processing raw data and generating plots for Figures 2 and 5 from [1].
