We propose a new sampling method to calculate the ground state of interactingquantum systems. This method, which we call the adaptive sampling quantum montecarlo (ASQMC) method utilises information from the high temperature densitymatrix derived from the monte carlo steps. With the ASQMC method, the negativesign ratio is greatly reduced and it becomes zero in the limit $\Delta \tau$goes to zero even without imposing any constraint such like the constraint path(CP) condition. Comparisons with numerical results obtained by using othermethods are made and we find the ASQMC method gives accurate results over wideregions of physical parameters values.Comment: 8 pages, 7 figure
