Abstract (in Japanese) (See Japanese page) 
(in English) A Quantum secret sharing (QSS) is a cryptographic scheme in which a secret quantum state is converted into multiple quantum states and those states are distributed to share holders, and only authorized share holders can recover the secret quantum state. A quantum single deletion-error code is a code that can restore the original quantum state from a state in which one of the encoded quantum states has been deleted. Quantum codes are sometimes used to construct QSS. In this paper, we confirm whether the quantum secret-sharing method can be realized using the Hagiwara code, one of the quantum deletion codes, and we also specify the access structure for this method. We have also verified whether obtaining the secret quantum state from the share using quantum entanglement and a quantum measurement. Countermeasures to this attack model will also be presented.
