An Efficient Parameterized Algorithm for Computing Quantum Channel Fidelity via Symmetries Exploitation

Determining the optimal fidelity for the transmission of quantum information over noisy quantum channels is one of the central problems in quantum information theory. Recently, [Berta-Borderi-Fawzi-Scholz, Mathematical Programming, 2021] introduced an asymptotically converging semidefinite programmi...
