Quantum Computation with Topological Phases of Matter
... charge-e/4 quasiparticle tunneling between the edges of a point contact in a non-Abelian model of the ν = 5/2 quantum Hall state. We map this problem to resonant tunneling between attractive Luttinger liquids and use the time-dependent density-matrix renormalization group (DMRG) method to compute th ...

Distinguishing mixed quantum states: Minimum
... In contrast to unambiguous discrimination, the earliest measurement strategy for distinguishing nonorthogonal quantum states requires that a definite, i.e., conclusive outcome is to be returned in each single measurement. This means that errors in the conclusive result are unavoidable and the discri ...
