A quantum computer executes quantum measurement of <ψ1|Pi|ψ2>, <ψ1|Uij,+|ψ2>, <ψ1|Uij,−|ψ2>, <ψ1|Pj|ψ2>, and <ψ1|PiPj|ψ2< below based on a quantum state pair configured by a first quantum state ψ1 and a second quantum state ψ2, and outputs measurement results of the quantum measurement. A classical computer computes a transition amplitude |<ψ1|A|ψ2>|2 based on measurement results for <ψ1|Pi|ψ2>, <ψ1|Uij,+|ψ2>, <ψ1|Uij,−|ψ2>, <ψ1|Pj|ψ2>, and <ψ1|PiPj|ψ2>, wherein A is a physical quantity for computation of transition amplitude, i and j are indices for identifying a and P, a is a real number, P is a tensor product of a Pauli matrix, U is a unitary gate, and <ψ1|ψ2>=0.
