摘要：

It is shown that the minimum energy required to transmit a natural unit of information (nat) over a noisy channel is kT, where T is the effective noise temperature which depends on the interaction between the information career and the environment. The result follows from the entropy defect principle and general laws of quantum dynamics without any specific assumptions. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
