" Possible exact threshold for toric code of quantum memory "
The error threshold of toric code, beyond which the stored quantum
state deteriorates, is closely related to the multicritical point of
the 2d spin glass. It is thus important to accurately determine the
location of the multicritical point of 2d spin glass systems. We have
developed a scheme to solve this problem, which is likely to give the
exact results, using duality arguments.
