Unmet Need
There is a need for improved quantum computing technology outside the standard superconducting loops where are currently in the process of being developed by a number of major corporations and research institutions. Superconducting loops require extensive cryogenic isolation and have comparably low longevity and logic success rates. In comparison when it’s finally realized topological quantum computing will allow for highly reduced error rates and cheaper qbits. These improvements would greatly facilitate the development of the quantum computing industry.  

Technology Overview
The technology developed is a flux qbit, the most basic unit of computing for a quantum computer, roughly analogous to a transistor in a common computer. The technology is also capable of operating in the absence of an external magnetic field. The flux qbit rests on the superposition of two degenerate ground states and the quantum states can be read by either measuring the magnetic flux or examining the direction of the supercurrent. This has the potential to be a foundational technology for the advancement of the field.
