If you can toggle a material from conductor to a Mott insulating state you can input a qubit and store it there. $\endgroup$ – Lawrence B. Crowell Dec 11 '16 at 13:04 Topological insulators could bring future computing platforms based on "spintronics." Conventional computers use the presence and absence of electric charges to represent ones and zeroes in a 2012-12-30 · A 3D topological insulator quantum dot for optically controlled quantum memory and quantum computing Hari P. Paudel, Michael N. Leuenberger (Submitted on 30 Dec 2012 (v1), last revised 1 Jun 2013 (this version, v2)) A primer on topological insulators The easiest way to describe a topological insulator is as an insulator that always has a metallic boundary when placed next to a vacuum or an ‘ordinary’ insulator. These metallic boundaries originate from topological invariants, which cannot change as long as a material remains insulating. Topological quantum computation is an approach to storing and manipulating quantum infor- mation that employs exotic quasiparticles, called anyons. Anyons are interesting on their own A topological quantum computer is a theoretical quantum computer proposed by Russian-American physicist Alexei Kitaev in 1997. It employs two-dimensional quasiparticles called anyons, whose world lines pass around one another to form braids in a three-dimensional spacetime (i.e., one temporal plus two spatial dimensions).

Quantum computing and spintronics: Topological insulators become a little less 'elusive' Date: May 12, 2015 Source: Sissa Medialab Summary: Topological insulators are "strange" materials $\begingroup$ A topological insulator is a way of storing a quantum bit. If you can toggle a material from conductor to a Mott insulating state you can input a qubit and store it there. $\endgroup$ – Lawrence B. Crowell Dec 11 '16 at 13:04 For example, by further combining topological insulators with a superconductor, which conducts electricity with no resistance, researchers may be able to build a practical quantum computer.
