PROBLEM TO BE SOLVED: To enable a data provider to provide only information of attributes required by a sampler while minimizing mutual information provision. SOLUTION: A data providing apparatus 10 generates a plurality of sets of first and second qubit strings, superposes element data in the first qubit strings, and superposes corresponding attribute data in the second qubit strings. The first and second qubit strings are entangled correspondingly. Only the second qubit strings are then sent to a sampling apparatus 30. The sampling apparatus 30 observes the second qubit strings, and selects such numbers of second qubit strings degenerated into attribute data to be sampled as are specified by sampling information. Request sample information indicating the selection content is next sent to the data providing apparatus 10. The data providing apparatus 10 returns the first qubit strings that match the request sample information, and the sampling apparatus 30 observes them. COPYRIGHT: (C)2005,JPO&NCIPI
