 ;</strong></p><p>Toric codes are prominent examples of quantum Hamiltonians
  that promise to encode quantum information in their ground states stably.&
 nbsp; In contact with a heat bath, the code’s quantum state will eventually
  converge to a Gibbs state. We investigate the mixing time of this process 
 when described by a Davis quantum Markovian semigroup. We establish a bound
  on the mixing time in the high-temperature regime, which is logarithmic in
  the system's size, thereby placing this class of&nbsp;quantum models on pa
 r with classical results on Glauber dynamics. This is done by establishing 
 a modified logarithmic Sobolev inequality.&nbsp;</p><p>In this talk, I will
  explain the models, the basic concepts, and the ideas behind the above res
 ult&nbsp; (joint work with Angela Capel, Cambyse Rouze and Sebastian&nbsp;S
 tengele).</p>
