Investigation of Quantum Computing With Laughlin Quasiparticles
Abstract
Laughlin quasiparticles of a gapped fractional quantum Hall (FQH) fluid, have been demonstrated to have fractional electric charge and anyonic braiding statistics. Topological computation with anyons has been proposed as the physical implementation of intrinsically fault-tolerant quantum computation (QC). Topological computation employs the statistical Berry phase created by the transfer of one anyon of the system around another to perform quantum logic. Since this phase is determined by the topological properties of the macroscopic FQH wave function, it is not sensitive to environment-induced decoherence and to spread of device parameters. The most thoroughly studied and realistic proposals involve the ground state adiabatic transport of anyons localized on quantum antidots and in anyon interferometers defined in GaAs/AlGaAs heterostructures. The device fabrication techniques and 2D architectures are similar to those commonly used in semiconductor industry, and thus are inherently scalable.
