conclusion, we have investigated qubit channels that prohibit the distribution of CHSH nonlocal states. On their own, such channels are useless for any quantum information task that involves CHSH nonlocality. However, the activation results presented can make these useless channels become useful particularly in instances of long-distance and noisy quantum communication. This work was supported by the National Science Foundation Award No.1839177. Y. Z and R. A .B contribute equally in this work.

N2 - We characterize CHSH-breaking conditions for different qubit channels, and demonstrate that certain pairs of CHSH-breaking channels can be activated to become CHSH-nonlocality preserving when used in parallel, thus enabling CHSH-nonlocality distribution through noisy channels.
