Title:
COMPUTATION SYSTEM
Document Type and Number:
Japanese Patent JP2023049249
Kind Code:
A
Abstract:
To calculate the relationship between elements constituting a knowledge graph by the use of a quantum computer.SOLUTION: A non-quantum computer 2 comprises: a triplet extraction part 211 which extracts from a knowledge graph a triplet of a head h, relation r and a tail t, in which one of two entities connected by the relation r is the head h and the other is the tail t; a quantum bit allocation part 212 which allocates unique quantum bits to the respective entities e; and a parameter initialization part 213 which sets a quantum conversion gate Ur(θ) and an initial value of the variable θ with respect to the relation r, the variable θ being a conversion parameter. A quantum computer 1 comprises: a quantum conversion part 10 which converts the head h and tail t with quantum conversion gates U(h) and U(t) respectively; and an evaluation value calculation part 11 which calculates a value of an evaluation function including the internal product of a quantum state obtained by converting a quantum bit after conversion of the head h with the quantum conversion gate Ur(θ) and a quantum bit after conversion of the tail t for the relation r, respectively.SELECTED DRAWING: Figure 3
