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.

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

These metallic boundaries originate from topological invariants, which cannot change as long as a material remains insulating.

In understanding these topological properties, it is equally important to study the mechanisms behind why topological insulators are ideal for applications of quantum computing. In particular, scientists have observed what is known as an "emergent" particle at the interface between two topological insulators, as referenced in an article However, quantum memories and quantum computing on a general basis are still technologies of the future. Note, for instance, the 3-μm scale of the measurement technique necessary to read the persistent spin polarization of the topological insulator.

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 insulators thus show great promise for quantum computing applications, where scattering from defects will destroy quantum information carried by electrons. In their study, researchers led by Albert Peruzzo of the RMIT University in Australia studied topologically protected states made of single photons rather than electrons. Topological insulators could bring future computing platforms based on "spintronics." Conventional computers use the presence and absence of electric charges to represent ones and zeroes in a 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.

The discovery both paves the way for more stable quantum computing and creates an entirely new platform to explore exotic physics.
