摘要：
A novel scheme of secure quantum addition module n + 1 (n >= 2) is proposed, based on non-orthogonal states, which allows a number to be added to an unknown number secretly. A proposed protocol for secure n-parity quantum summation is quasisecure to Eve. The collusive attack performed by n-1 legitimate participators cannot eavesdrop all the input information of the other participator in the protocol.
