  We test the AdS/CFT correspondence by calculating Wilson loops in N = 4 super
Yang-Mills theory on R*S^3 in the planar limit. Our method is based on a novel
large-N reduction, which reduces the problem to Monte Carlo calculations in the
plane-wave matrix model or the BMN matrix model, which is a 1d gauge theory
with 16 supercharges. By using the gauge-fixed momentumspace simulation, we
obtain results respecting 16 supersymmetries. We report on the Monte Carlo
results for the BPS circular Wilson loop, which reproduce the exact result up
to strong coupling. As a future prospect, we calculate a track-shapedWilson
loop from the gravity side, which shows that a clear test of the AdS/CFT for
the non-BPS case is also feasible.
