Efficiently computing the Uhlmann fidelity for density matrices
Physical Review A American Physical Society 107 (2023) 012427
Abstract:
We consider the problem of efficiently computing the Uhlmann fidelity in the case when explicit density matrix descriptions are available. We derive an alternative formula which is simpler to evaluate numerically, saving a factor of 10 in time for large matrices.Efficiently computing the Uhlmann fidelity for density matrices
