Topological quantum computing with only one mobile quasiparticle.
In a topological quantum computer, universal quantum computation is performed by dragging quasiparticle excitations of certain two dimensional systems around each other to form braids of their world lines in 2 + 1 dimensional space-time. In this Letter we show that any such quantum computation that can be done by braiding n identical quasiparticles can also be done by moving a single quasiparti...
متن کاملMeasurement-only topological quantum computation.
We remove the need to physically transport computational anyons around each other from the implementation of computational gates in topological quantum computing. By using an anyonic analog of quantum state teleportation, we show how the braiding transformations used to generate computational gates may be produced through a series of topological charge measurements.
متن کاملTopological Quantum Computing
Quantum computers have the ability to solve certain problems exponentially faster than the best known algorithms for classical computers. Examples include database searching, simulation of quantum systems, and factoring large numbers.[1][2][3] However, the nature of most quantum systems makes the states too fragile for efficient calculations to be done. Topological quantum computing avoids thes...
متن کاملTopological quantum computing with Read-Rezayi states.
Read-Rezayi fractional quantum Hall states are among the prime candidates for realizing non-Abelian anyons which, in principle, can be used for topological quantum computation. We present a prescription for efficiently finding braids which can be used to carry out a universal set of quantum gates on encoded qubits based on anyons of the Read-Rezayi states with k>2, k not equal 4. This work exte...
متن کاملMathematics of Topological Quantum Computing
In topological quantum computing, information is encoded in “knotted” quantum states of topological phases of matter, thus being locked into topology to prevent decay. Topological precision has been confirmed in quantum Hall liquids by experiments to an accuracy of 10−10 and harnessed to stabilize quantum memory. In this survey, we discuss the conceptual development of this interdisciplinary fi...
