Quantum Computing with a Topological Phase of Matter

March 31, 2020

A central tenet of condensed matter physics is that the collective behavior of a system can be drastically different from that of its constituent parts.  Topological phases of matter provide an especially dramatic example of this idea: the phase of matter cannot be identified within a local region, but is rather encoded in global properties of the system.  As such, topological phases are insensitive to local noise, making them a promising platform for fault tolerant quantum computing.  In this talk, we will explore how to build a quantum computer out of a topological superconductor.  We will first cover what a topological superconductor is, and the current state of experiments.  We will then describe how to build qubits from topological superconductors and their protection from a noisy local environment.
