"According to the laws of quantum physics, electrons are waves as well as particles. Like ocean waves, where two crests meet they reinforce each other and where a crest and trough meet they cancel each other out. Traditional electronic computers use combinations of transistors, which are tiny electronic switches, as the logic units that perform the binary arithmetic at the heart of digital computing. Electron wave computers would use networks of microscopic wire rings that form the two paths for the electron waves to follow.

Using a magnetic field perpendicular to the ring, researchers can speed up or slow down the electron wave traveling in one side of the ring, throwing the waves in the two sides out of sync and causing the waves to cancel each other out when they meet at the other end. The reinforced waves and the canceled waves could represent the ones and zeros of computing, as developed by Wu. Three-terminal A-B rings could be combined to form various logic units [1], In an attempt to build higher order logic devices using these rings, an 8X8 QRN was modeled.

Modified forms of 3 and 4-terminal Aharonov-Bohm rings have been investigated by Ramamurthy and Wu. In this thesis a network of interconnected 4 terminal rings that forms an 8X8 array is investigated. Possible quantum computing applications are studied in both digital and analog areas"--Abstract, page iii.
