The thermalization process of the 2D Kitaev model is studied within the Markovian weak coupling approximation. It is shown that its largest relaxation time is bounded from above by a constant independent of the system size and proportional to exp(2Δ/kT), where Δ is an energy gap over the four-fold degenerate ground state. This means that the 2D Kitaev model is not an example of a memory, neither quantum nor classical.

• Quantum memories at finite temperature (2014, methodology): “(Alicki et al., 2009; Nussinov and Ortiz, 2008), but ultimately follows from the fact that one can find a sequence of single qubit error operations that will realize a logical operator without increasing the energy of the system beyond a constant value that is independent of the system size.”
