Title: Price evaluation system and price evaluation method
Inventor: UNO SHUMPEI
IPC: G06Q10/04
Filed: 2021-05-11
Abstract: To provide a price evaluation system and a price evaluation method for calculating an expectation value in an object to be evaluated while reducing noise by using amplitude estimation through quantum calculation.SOLUTION: An operating unit 221 of an arithmetic unit 20 acquires a first operator that produces a superposition state of scenarios of future price movement of a financial product, and generates a second state by performing inversion arithmetic in an initial state by applying a Hermitian conjugate of the first operator to a quantum state where the last bit of a bit string is "0." A measuring unit 223 performs measurement of the bit string for a quantum state created by repeating an operation to produce a third state in which inversion arithmetic of the second state is performed for the initial state by using a state holding unit 222, and records the number of hits where all bits are "0" in a classical calculation unit 23. The classical calculation unit 23 performs price evaluation of the financial product through maximum likelihood estimation according to the number of repetition and the number of hits.SELECTED DRAWING: Figure 1
