Direct relationship between quantum state splitting and channel simulation simplifies the process.
Statisztikák
Recent years have seen studies on different regimes like one-shot no-signaling-assisted regime, moderate deviation regime, and network setups.
The fidelity between joint input-output density operators is quasi-convex w.r.t. input density operator and concave w.r.t. protocol.
Sion’s minimax theorem is applied to show equivalence between best/worst protocols for channel simulation under same communication constraint.
Idézetek
"The optimal performance of channel simulations is directly determined by the optimal performance of quantum state transfers."
"Direct relationship established between state splitting protocols and achieving tighter bounds in one-shot achievability."
