Variational quantum-algorithm based self-consistent calculations for the two-site DMFT model on noisy quantum computing hardware
The work tested using a Variational Quantum Eigensolver (VQE) simulation to solve the two-site Dynamical Mean Field Theory (DMFT) model on noisy quantum hardware. By mapping the problem onto qubits and analyzing noise, the study found that statistical noise causes unphysical results in self-energy calculations near zero frequency, which is mitigated using a fitting approach.
