摘要：

We discuss a long-term solution for realizing the power minimum ICT, revisiting the fundamental laws of physics. In particular, we focus on a new paradigm of quantum information and communications technology (Q-ICT), in the context of reducing the power consumption in optical fiber communications. Our analysis shows that quantum communications will be able to reduce the transmission power by more than 40 dB from current technology. The key is a technology of quantum collective decoding at the receiver side.
