For tsese two yeras D0-brane quantum mechanics, which is conjectured to be dual to type IIB superstring theory, has been studied numericaly.
Results obtained so far are consistent with the duality in the planar limit and alpha-prime correction to the supergravity was correctly reproduced from the gauge theory. In this talk I would like to show recent numerical results on the 1/N correction and discuss its relation to finite string coupling correction.
