From there, I discovered a bounty of articles that are at once cogent, detailed, and edifying. This post is meant to be a well-rounded yet playful, approachable, and non-technical reading list for those interested in learning about major trends in blockchain and cryptocurrencies.
The principle was described by Paul Dirac as follows: The general principle of superposition of quantum mechanics applies to the states [that are theoretically possible without mutual interference or contradiction] It requires us to assume that between these states there exist peculiar relationships such that whenever the system is definitely in one state we can consider it as being partly in each of two or more other states.
The original state must be regarded as the result of a kind of superposition of the two or more new states, in a way that cannot be conceived on classical ideas. Any state may be considered as the result of a superposition of two or more other states, and indeed in an infinite number of ways.
Conversely any two or more states may be superposed to give a new state The non-classical nature of the superposition process is brought out clearly if we consider the superposition of two states, A and B, such that there exists an observation which, when made on the system in state A, is certain to lead to one particular result, a say, and when made on the system in state B is certain to lead to some different result, b say.
What will be the result of the observation when made on the system in the superposed state? The answer is that the result will be sometimes a and sometimes b, according to a probability law depending on the relative weights of A and B in the superposition process. It will never be different from both a and b [i.
The intermediate character of the state formed by superposition thus expresses itself through the probability of a particular result for an observation being intermediate between the corresponding probabilities for the original states, not through the result itself being intermediate between the corresponding results for the original states.
It is important to realize that this does not imply that an observer actually takes note of what happens. When this is true the equation is said to obey the superposition principle.
For example, consider an electron with two possible configurations, up and down. This describes the physical system of a qubit.Read this essay on Cryptography.

are available § Understand that PKI is NOT the same thing as public key encryption Fundamentals of Information Systems . Applications of information theory Data compression.
Shannon’s concept of entropy (a measure of the maximum possible efficiency of any encoding scheme) can be used to determine the maximum theoretical compression for a given message alphabet.
In particular, if the entropy is less than the average length of an encoding, compression is possible. This paper provides quantitative data that, in many cases, open source software / free software is equal to or superior to their proprietary competition.
The paper examines market share, reliability, performance, scalability, scaleability, security, and total cost of ownership; it also comments on non-quantitative issues and unnecessary fears.
