Phys. Rev. Lett. 98, 160502 (2007) [4 pages]Topological Computation without BraidingReceived 13 September 2006; published 19 April 2007 We show that universal quantum computation can be performed within the ground state of a topologically ordered quantum system, which is a naturally protected quantum memory. In particular, we show how this can be achieved using brane-net condensates in 3-colexes. The universal set of gates is implemented without selective addressing of physical qubits and, being fully topologically protected, it does not rely on quasiparticle excitations or their braiding. © 2007 The American Physical Society URL:
