Solving the homogeneous Bethe-Salpeter equation with a quantum annealer
Filippo Fornetti, Alex Gnech, Tobias Frederico +6
The homogeneous Bethe-Salpeter equation (hBSE), describing a bound system in a genuinely relativistic quantum-field theory framework, was solved for the first time by using a D-Wav…
