This project works toward "topological quantum computing" by developing Majorana fermions, in heterostructures based on high-quality topological insulators.

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 Although the topological insulating phenomenon was observed at up to 100 kelvins, the superconducting behavior in the new work occurred at a much lower temperature of about 1K. This material has the advantage of entering the superconducting state with one of the lowest densities of electrons for any 2 … 2015-10-27 Inducing high-temperature superconductivity on the surface of a topological insulator opens the door to the creation of a pre-requisite for fault-tolerant quantum computing, a mysterious 2013-09-16 2017-01-18 Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducted states on their edge or surface. These states are possible due to the combination of spin-orbit interactions and time-reversal symmetry. The two-dimensional (2D) topological insulator is a quantum 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. Recently, a new class of topological states has emerged, called quantum spin Hall (QSH) states or topological insulators (see Physics Today, January 2008, page 19).Topologically distinct from all other known states of matter, including QH states, QSH states have been theoretically predicted and experimentally observed in mercury telluride quantum wells, 2,3 2.

However, the initial measurements all indicated that they only had standard superconductivity induced in the Bi2Te3 topological insulator. T opological quantum computing is an approach to fault-tolerant quantum computation, where the protection from errors occurs not from active intervention, but at a hardw are level. The The bulk core of the sandwich is the topological insulator, made from a few quintuple layers of bismuth antimony tellurium selenide (Bi 2-x Sb x Te 3-y Se y).

$\begingroup$ 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

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.

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. Topological insulators were first realized in 2D in system containing HgTe quantum wells sandwiched between cadmium telluride in 2007. The first 3D topological insulator to be realized experimentally was Bi 1 − x Sb x. 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.

$\endgroup$ – Lawrence B. Crowell Dec 11 '16 at 13:04 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). One example of an application for topological materials is for quantum computing devices and platforms.

This technology would allow for the eventual construction of the quantum computer, a revolutionary device that would use the dynamics of atomic-scale objects to store and manipulate information. However, quantum memories and quantum computing on a general basis are still technologies of the future. Note, for instance, the 3-μm scale of the measurement technique necessary to read the persistent spin polarization of the topological insulator. Recording the up or down state.
