There are stark differences between metals, through which electrons flow freely, and electrical insulators, in which electrons are essentially immobile. And despite the obvious difficulties in finding...
A statistical-mechanical view on source coding: physical compression and data compression
statistical-mechanical physical compression data compression
2010/11/23
We draw a certain analogy between the classical information–theoretic problem of lossy data compression (source coding) of memoryless information sources and the statistical mechanical behavior of a c...

nse-Coding Attack Three-Party Quantum Key Distribution Protocols
2010/10/19
Cryptanalysis is an important branch in the study of cryptography, including both the classical cryptography and the quantum one. In this paper we analyze the security of two three-party quantum key d...
Beating the channel capacity limit for linear photonic superdense coding
channel capacity limit linear photonic superdense coding
2010/10/21
Dense coding is arguably the protocol that launched the field of quantum communication [1]. Today,however, more than a decade after its initial experimental realization [2], the channel capacity remai...
A Coding of Real Null Four-Momenta into World-Sheet Coordinates
maximally violating helicity World-Sheet Coordinates Real Null Four-Momenta
2009/9/4
The results of minimizing the action for string-like systems on a simply connected world sheet are shown to encode the Cartesian components of real null momentum four-vectors into coordinates on the w...
The generation of Entangled Qudits and their Application in Probabilistic Superdense Coding
generation of Entangled Qudits Application Probabilistic Superdense Coding
2013/7/3
A scheme of the generation of entangled qutrits is presented, and then is generalized to entangled ququads and entangled qudits. With the entangled qutrits, an experimental scheme of probability super...
