| Outline of Final Research Achievements |
In this project, we introduced a notion of t-MOD, which is a mathematical formulation of a quantum jump code related to the error correction of memories of a quantum computer. A complete t-MOD with maximum dimension among t-MODs with given length and error correcting ability is considered and its combinatorial structure is characterized. We gave some nonexistence results of complete t-MOD and a example of a complete 1-MOD.
On the other hand, we obtain constructions of a binary t-MOD, called a t-SEED, by utilizing affine geometry. Moreover, we find a sufficient condition by introducing the notion of`lcm-closure' to the multifold factorization problem of cyclic groups, which is closely related to the construction of 2-SEEDs.
