The two-dimensional (2D) topological insulator is a quantum Topological insulators (TI) have potential future application in quantum computers 1-3 and spintronics [4][5] [6] owing to existence of symmetry protected edge or surface states, and also provide Topological quantum computation is a computational paradigm based on topological phases of matter, which are governed by topological quantum field theories. In this approach, information is stored in the lowest energy states of many-anyon systems and processed by braiding non-abelian anyons. The computational answer is accessed by bringing anyons together and observing the result. Besides […] 2015-10-27 · Topological quantum computation 1,2 is an approach to fault-tolerant quantum computation in which the unitary quantum gates result from the braiding of certain topological quantum objects called 2 dagar sedan · Said Professor Lado, ‘Ultimately, engineering these valley states can allow realizing quantum entangled valley liquids and fractional quantum valley Hall states. These two exotic states of matter have not been found in nature yet, and would open exciting possibilities towards a potentially new graphene-based platform for topological quantum computing.’ 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 topological quantum computing with these Majoranas.

Topological insulator quantum computing

2019-02-28 "The superconducting pair of electrons then leak into the topological insulator, which also becomes superconducting," explains Thilo Bauch, associate professor in quantum device physics. However, the initial measurements all indicated that they only had standard superconductivity induced in the Bi2Te3 topological insulator.

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 2012-12-30 2021-01-29 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.

2013-09-16 · Utilizing topological insulators is considered one promising approach for solving this “decoherence” problem because qubits in a topological quantum computer would be made from Majorana zero modes, which are naturally immune from decoherence. Information processed and stored in such topological qubits would always be preserved. 2019-02-28 · Termed a “topological insulator”, the strip, when connected to two superconductor electrical leads composes a device called a “Josephson Junction.” Why Is this Needed?

Professor Steve Simon, Department of Physics at Oxford University, lectures on topological quantum computing. The lecture is the first of two parts, and was Majorana Fermions in Topological Insulators I. Introduction - Topological band theory and topological insulators II. Two Dimensions : Quantum Spin Hall Effect - Time reversal symmetry and edge states - Experiment: Transport in HgTe quantum Wells III. Three Dimensions : Topological Insulators - Topological Insulator Surface States 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. 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.
