2 Dec 2020 Zhang's research builds on the science of topological insulators, which are it to make influential future devices such as a quantum computer.

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.

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. "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. 2021-02-18 2018-02-19 “Topological insulators could be an important material in future quantum computing.

Topological insulators could offer a way to harness exotic particles for quantum computing. 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 have predicted 1. Nearly every fundamental particle has an antiparticle counterpart with the same 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 Outlook Quantum Computing Springholz says these self-organization phenomena could be leveraged in particular ways to develop entirely new configurations for magnetic topological materials. 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. Topological insulators’ properties make these materials appealing for new technologies that require quantum-level manipulations. Chen, whose laboratory focuses on improving the quality of existing topological insulators, points to spintronics as a field likely to benefit from the material.

Topological insulator quantum computing

“In a quantum computer, a qubit ‘entangles’ with other qubits. 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. topological quantum computing with these Majoranas.

$\endgroup$ – 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 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. 2015-05-12 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.
