Hello fellow Wikipedians,

I have just added archive links to 1 one external link on Quantum technology. Please take a moment to review my edit. If necessary, add after the link to keep me from modifying it. Alternatively, you can add to keep me off the page altogether. I made the following changes:
 * Added archive https://web.archive.org/20070830190154/http://www.physics.uq.edu.au/people/milburn/books/Schr_Mach.html to http://www.physics.uq.edu.au/people/milburn/books/Schr_Mach.html

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Qubit Computing: Analog-to-Digital Computing
Qubit Computing is a new kind of information processor based off of quantum mechanics and involving a single qubit. An analog signal f(n) is represented by the state sqrt(1/f(n)) ket(0) + sqrt(1 - 1/f(n)) ket(1), and this value can me measured for each of value of n by preparing and measuring the state repeatedly, distinguishing 0's and 1's, and deducing the fraction of 0's to 1's as |1/(f(n))|^2. Hence the output is digital. This is also a sixth way of representing information, the other ways being classical digital-to-digital, classical analog-to-analog, stochastic digital-digital, stochastic analog-to-analog, quantum computing digital-to-digital, and qubit computing analog-to-digital. In particular if f(n) = n one can count amongst the set of natural numbers. This was published recently on ResearchGate https://www.researchgate.net/publication/344239568_Circuit_Design_of_a_Qubit_Counter. This is not the same as an analog-to-digital converter, which has a circuit that converts an analog value to a digital value. I think the time is right that this should be posted on Wikipedia so that anybody, especially researchers, can make use of the information.
