The question isn't why do we want one,

 it is how do we build one…

​

There are many approaches to the construction of a quantum computer being studied today. Each approach comes with limitations, drawbacks, and challenges. These include low-temperature requirements, phase coherence limits and scalability restrictions. Error sources and propagation are among the biggest concerns.

Instead the QCWG team pursues much different and riskier pathways than those typical in the field. Our approach uses the symmetry preserving properties of complex topologies constructed on 2D manifolds to build robust Qubits/Quregisters. That topology can allow for significant hardness against the environment is a concept we call the stabilization conjecture and it is just one of the ways we try to approach higher temperature operation in quantum hardware.

​

This is the core behind - QCWG - an attempt at realizing an architecture for general processing that is mobile, robust and scalable.​
