Outline of Final Research Achievements

In this project, the following results for combinatorial structures related to information communication systems are obtained. (i) Constructions of conflict-avoiding codes with weights three and four are obtained. (ii) Constructions of affine-invariant SQSs are obtained. (iii) Quantum jump codes are charactelized as families of mutually orthogonal t-designs and their existence are discussed. (iv) Constructions of some optimal Euclidean designs on concentric spheres are obtained. (v) Optimality, in the sense of detecting probability of positive items, of a regular bipartite graph representing a group testing is clarified.
