IOP publishing group has released a new book on quantum communications titled An Introduction to Quantum Communications Networks: Or, how shall we communicate in the quantum era? by Mohsen Razavi at University of Leeds.

Abstract. This book fills a gap between experts and non-experts in the field by providing readers with the basic tools to understand the latest developments in quantum communications and its future directions. With the fast pace of developments in quantum technologies, it is more necessary than ever to make the new generation of students in science/engineering familiar with the key ideas behind such disruptive systems. This book describes key applications for quantum networks; local, metropolitan, and global networks; and the industrial outlook for the field.

Information is the resolution of uncertainty …

Claude Shannon

Just learnt about an interesting article by a friend. Find cool stuff addressing the Maxwell’s demon, Zilard engine, Landauer’s principle and their experimental realizations in Physics Today. You’ll also find out more fascinating stuff: information values that are tightly connected to entropy and energy; what I call ‘inforogy’!

I hope I can someday learn all about the Maxwell’s demon 🙂

Here is another submission on the subject: Information gain and loss for a quantum Maxwell’s demon.

I’m interested in the `history’ of the Maxwell demon. I’m not sure if I can understand the current work; yet I liked that it is  “dedicated to the memory of Marian Smoluchowski, the most successful Maxwell demon exorcist in the 100 anniversary of his death”.
