Title:
QUANTUM INFORMATION PROCESSING SYSTEM, QUANTUM INFORMATION PROCESSING METHOD, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2017/131081
Kind Code:
A1
Abstract:
The present invention provides a quantum information processing system, a quantum information processing method, a program, and a recording medium whereby the complexity of the real-time dynamics of a quantum system can be applied to the nonlinear time-series data processing in high demand in the machine learning field. The present invention is provided with: a quantum reservoir that includes a quantum system constituted from a plurality of mutually interacting quantum bits and provided with a plurality of virtual nodes for holding a signal from each of the quantum bits at each of a plurality of clock times into which a fixed time interval is divided; a weight determination unit for determining a linear weight in a linear combination of the plurality of virtual nodes; a signal input unit for allotting an input signal to one of the quantum bits at the time interval; and a signal readout unit for reading out an output signal obtained from the superposition of states of the virtual nodes linearly combined using the linear weight determined by the weight determination for the input signal allotted by the signal input unit.
