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.

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. 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. Quantum computers should be capable of performing tasks that would be very difficult, if not impossible, with digital computers, such as finding the prime factors of large numbers, searching large databases, and simulating quantum systems.
Image source: Purdue University image/Jifa Tian. A three-dimensional (3D) topological insulator (TI) is a quantum state of matter with a gapped insulating bulk yet a conducting surface hosting topologically-protected gapless surface states. Quantum Computation is any computational model based upon the theoretical ability to manufacture, manipulate and measure quantum states. A topological quantum computer is a device that relies upon Note that the gapless surface states of topological insulators differ from those in the quantum Hall effect: the gapless surface states of topological insulators are symmetry-protected (i.e., not topological), while the gapless surface states in quantum Hall effect are topological (i.e., robust against any local perturbations that can break all $\begingroup$ 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 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).

Substantial effort has been directed towards realizing topological insulators for electromagnetic waves. And on the way to topological quantum computing, researchers can explore more exotic physics, including the topological Kondo effect.
