The weak measurement and measurement reversal processes require the implementation of non-unitary operations, which are typically infeasible on conventional quantum processors, where only unitary quantum operations are allowed. The duality quantum algorithm is used to efficiently implement the required non-unitary quantum operations corresponding to weak measurement and measurement reversal.
