The first part of the lecture notes covers the basics of abelian and non-abelian anyons and their realization in the Kitaev's honeycomb model. The second part discusses how to “Topological insulators could be an important material in future quantum computing. Our findings have uncovered a new limitation in this system,” said Vikram Deshpande, assistant professor of physics at the University of Utah and corresponding author of the study. A topological insulator is mainly just an insulator – in other words it does not conduct current – but it conducts current in a very special way on the surface. The researchers have placed a layer of a conventional superconductor on top, in this case aluminium, which conducts current entirely without resistance at really low temperatures. Topological insulators thus show great promise for quantum computing applications, where scattering from defects will destroy quantum information carried by electrons. In their study, researchers led by Albert Peruzzo of the RMIT University in Australia studied topologically protected states made of single photons rather than electrons.
Purdue University doctoral student Yang Xu, lead author of a new research paper on "topological insulators," an emerging class of materials that could make possible "spintronic" devices and practical quantum computers far more powerful than today's technologies, is shown here inspecting devices made from topological insulators under a microscope before electrical measurements. 2018-04-30 Photonic topological insulator could enable quantum computing Ashley N. Rice, [email protected] As computers get faster and chips get denser, there is a need for smaller light-manipulating devices. Researchers have uncovered "smoking-gun" evidence to confirm the workings of an emerging class of materials that could make possible "spintronic" devices and practical quantum computers far more powerful than today's technologies. The postdoc will join our circuit quantum electrodynamics (cQED) team within Ando lab. Responsibilities would be design, simulation, fabrication, and measurement of cQED devices at gigahertz frequencies. Devices will integrate topological-insulator Josephson junctions into circuits, including transmon and RF-SQUID type designs.

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).

Anyons are interesting on their own 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 materials are a class of compounds featuring electronic band structures, which are topologically distinct from common metals and insulators. These materials have emerged as exceptionally fertile ground for materials science research.
Bismuth in its pure state, is a semimetal with a small electronic band gap. Topological insulators could offer a way to harness exotic particles for quantum computing. A broad class of quantum materials could be used to create particles that may find use in quantum computers, calculations by two RIKEN theoretical physicists have predicted 1. Nearly every fundamental particle has an antiparticle counterpart with the same Outlook Quantum Computing Springholz says these self-organization phenomena could be leveraged in particular ways to develop entirely new configurations for magnetic topological materials. As a rule, the gap that has been quantified now is already so wide that it must facilitate the development of a near-room-temperature QAHE from suitable components. Topological insulators thus show great promise for quantum computing applications, where scattering from defects will destroy quantum information carried by electrons.
