Abstract
A system obtains an operator that produces a superposition state of a plurality of random variables. The system performs iteration of a first operation and a second operation on an initial quantum state to produce a final quantum state. The first operation produces a second state by performing a computation that inverts a first state with respect to a state obtained by applying a Hermitian conjugate of the operator to a quantum state where the last bit of a bit string is 0. The second operation produces a new first state by performing a computation that inverts the second state with respect to the first state. The system measures the bit string in the final quantum state, records the number of times a quantum state where all bits of the bit string are 0 is observed, and calculate an expectation value of the random variables according to the number.
