“In a quantum computer, a qubit ‘entangles’ with other qubits. Topological insulators in three dimensions are quite far from the classical Hall e ect. They are characterized by the topological property of having con-ducting interfaces paired with an insulating bulk. A QSH system is actually a two dimensional topological insulator.

Topological insulator quantum computing

Materials with these qualities are sought for spintronic and quantum computing devices. 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.

Quantum computing and spintronics: Topological insulators become a little less 'elusive' Date: May 12, 2015 Source: Sissa Medialab Summary: Topological insulators are "strange" materials $\begingroup$ 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 For example, by further combining topological insulators with a superconductor, which conducts electricity with no resistance, researchers may be able to build a practical quantum computer. Such a technology would perform calculations using the laws of quantum mechanics, making for computers much faster than conventional computers at certain The hallmark of a topological insulator is the existence of metallic surface states that are higher-dimensional analogues of the edge states that characterize a quantum spin Hall insulator. In addition to its interesting boundary states, the bulk of Bi(1-x)Sb(x) is predicted to exhibit three-dimensional Dirac particles, another topic of Topological insulators were first realized in 2D in system containing HgTe quantum wells sandwiched between cadmium telluride in 2007.

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 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). 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. 2012-12-30 · Title: A 3D topological insulator quantum dot for optically controlled quantum memory and quantum computing Authors: Hari P.
