Topological quantum computation on supersymmetric spin chains

Pramod Padmanabhan


A promising route for fault-tolerant quantum computing is by using the fusion spaces of anyons as they support representations of the braid group. Quantum gates built out of the corresponding braid group elements are naturally insensitive to perturbations making the entire setup desirable for quantum computing. However, anyons that can provide universal gates have still been elusive in experiments prompting the need to look for alternate sources. In this talk, I will show that the zero modes of SUSY spin chains can mimic the effects of anyons and thus providing an alternative for realising a quantum computer on magnetic systems.

The talk will be based on
