Asymptotics of quantum channels

Quantum hardware, including quantum computers, faces challenges due to noise and decoherence. Asymptotic dynamics in open quantum systems offer opportunities for implementing noise-protected unitary operations. By explicitly defining the asymptotic map, we show how permutations affect this evolution. These permutations typically make the process non-unitary and depend on how divisible the quantum channel is.
