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.

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.

2019-07-01 Topological insulators could offer a way to harness exotic particles for quantum computing. A large class of quantum materials could host hypothetical particles useful for quantum computers. 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 Topological insulators provide a boost for quantum computing Posted on April 24, 2017 by Electronic Products Neither conductor nor insulator, this material can record “one” or “zero” on a subatomic level, with major implications for future computer memories $\begingroup$ 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 2021-01-29 2012-12-30 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 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 insulator quantum computing

Photonic Topological Quantum Computer Scientists have developed a topological photonic chip to process quantum information, promising a more robust option for scalable quantum computers. W With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. A New FLEET research confirms the potential for topological materials to substantially reduce the energy consumed by computing. The collaboration of FLEET researchers from University of Wollongong, Monash University and UNSW have shown in a theoretical study that using topological insulators rather than conventional semiconductors to make transistors could reduce the gate voltage by half, and 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). This core is sandwiched by a few layers of boron nitride, and is topped off with two layers of graphite, above and below. 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-D superconductor.

Topological insulators is an example of a new class of quantum materials that is on precision measurement and topologically protected quantum computation.

“People working with topological insulators need to know what their limits are.

Substantial effort has been directed towards realizing topological insulators for electromagnetic waves. 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. 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 And on the way to topological quantum computing, researchers can explore more exotic physics, including the topological Kondo effect. That phenomenon exploits the analogy between the two degenerate parity ground states formed by two highly nonlocal Majoranas and the spin-½ system of the standard Kondo effect.
