Incoherent dynamics in the toric code subject to disorder
Beat Röthlisberger, James R. Wootton, Robert M. Heath +2
We numerically study the effects of two forms of quenched disorder on the anyons of the toric code. Firstly, a new class of codes based on random lattices of stabilizer operators i…
Self-Correcting Quantum Memory in a Thermal Environment
Stefano Chesi, Beat Röthlisberger, Daniel Loss
The ability to store information is of fundamental importance to any computer, be it classical or quantum. To identify systems for quantum memories which rely, analogously to class…
Numerical evaluation of convex-roof entanglement measures with applications to spin rings
Beat Röthlisberger, Jörg Lehmann, Daniel Loss
We present two ready-to-use numerical algorithms to evaluate convex-roof extensions of arbitrary pure-state entanglement monotones. Their implementation leaves the user merely with…
