Topological quantum codes in the presence of asymmetric noise

Topographical quantum codes are of special importance in quantum computing due to their inherent robustness to local disturbances, and numerous researches are underway on the robustness of these codes as well as the error tolerance threshold of such codes. On the other hand, recently and based on the studies conducted on current quantum computers, it has been shown that the noises in the laboratory are asymmetric, contrary to expectations. Fortunately, recent research shows that with a simple change in topological codes, this asymmetry can be used to increase fault tolerance. In this lecture, we will briefly introduce this idea.
