Entangled states are harder to transfer than product states

HIGHLIGHTS

• who: Tony J. G. Apollaro et al. from the Department of Physics, University of Malta, MSD , Msida, Malta, Italy have published the research: Entangled States Are Harder to Transfer than Product States, in the Journal: Entropy 2023, 25, 46. of /2023/
• what: Building on recent results reporting the fidelity of an n-qubits QST (n-QST) protocol for arbitrary quantum channels, the authors investigate the effect of the presence of entanglement on the n-QST fidelity, which is evaluated when each qubit is subject to an independent U -symmetric quantum channel, e_g, an amplitude-damping . . .
