A statistical mechanics view on Kitaev's proposal for quantum memories
A statistical mechanics view on Kitaev's proposal for quantum memories
We compute rigorously the ground and equilibrium states for Kitaev's model in 2D, both the finite and infinite version, using an analogy with the 1D Ising ferromagnet. Next, we investigate the structure of the reduced dynamics in the presence of thermal baths in the Markovian regime. Special attention is paid …
