Description
In Quantum Hall effect the ground state wave function at ν = 1 is the building block of all other states at different filling factors. It is formed by the entanglement of two spinors forming a singlet state. The inherent frustration visualized by the non-abelian matrix Berry phase is responsible for the quantum pumped charge to flow in the Hall surface. In the light of topological quantum computation the Physics behind Quantum Hall states is studied. (author)
