It has been well known since the pioneering work of Claude Shannon in the 1940s that a message transmitted with optimal efficiency over a channel of limited bandwidth is indistinguishable from random noise to a receiver who is unfamiliar with the language in which the message is written. We derive some similar results about electromagnetic transmissions. In particular, we show that if electromagnetic radiation is used as a transmission medium, the most information-efficient format for a given…

Quantum Limits on the Entropy of Bandlimited Radiation

The derivation first considers an optimal subspace approximation, and then determines the number of bits that are required to represent any waveform in the space spanned by this representation with a minimum quantized energy error, favors a geometric interpretation where the complexity of state counting is replaced by the one of determining the minimum cardinality covering of the signal space by high-dimensional balls, or boxes, whose size is lower bounded by quantum constraints.

Wave Theory of Information

Information-theoretic laws relating functional approximation and quantum uncertainty principles to entropy, capacity, mutual information, rate–distortion, and degrees of freedom of bandlimited radiation are derived and explained.

Analogue circuits for low power communication

The energy requirements of amplification are presented and a lower bound on the energy required to transmit information over a point to point link is proposed and it is evident from the low power limits survey that when a transistor is biased, significant thermodynamic energy is required to reduce the resistance of the channel.

Entropy fundamental concept crosses so many scientific and research areas, but, unfortunately, scientists have not yet worked out a definitive solution to the fundamental problem of the logical relationship between human experience and knowledge extraction.

It is shown that acceleration of a receiver acts to block information transfer, and the time-energy uncertainty principle is reformulated in information language by means of the linear bound.

It is proved that the authors can get some positive data rate that has the same small error probability and also there is an upper bound of the data rate, which means they cannot achieve the data rates with any encoding scheme that has small enough error probability over the upper bound.

The possible amount of information transfer between any source and any user via a quantum system is bounded through the quantum entropy function, which shows that infinite information transfer implies infinite entropy.
