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

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.

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. 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.

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 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. 2021-04-12 2016-09-13 These findings taken together suggest that the observed surface state on the boundary of the bulk insulator is a realization of the 'topological metal'. They also suggest that this material has potential application in developing next-generation quantum computing devices that may incorporate 'light-like' bulk carriers and spin-textured surface currents.
