    "abstract": "We study the effect of thermal fluctuations in a recently proposed protocol\nfor transmission of unknown quantum states through quantum spin chains. We\ndevelop a low temperature expansion for general spin chains. We then apply this\nformalism to study exactly thermal effects on short spin chains of four spins.\nWe show that optimal times for extraction of output states are almost\nindependent of the temperature which lowers only the fidelity of the channel.\nMoreover we show that thermal effects are smaller in the anti-ferromagnetic\nchains than the ferromagnetic ones.",
