This device enables the observation of quantum behaviors of atomic nuclei and aims to demonstrate quantum algorithms for students. Successfully executing quantum algorithms requires enhancing the signal-to-noise ratio (S/N). One approach involves extending accumulation times. However, the magnetic field generated by a pair of Ferrite magnets in this device is temperature-sensitive; even minor room temperature changes cause data accumulation failure. To tackle this problem, we devised a program capable of accumulating data while monitoring temperature changes by observing NMR signals themselves. This approach allowed us to conduct lengthier accumulations and effectively implement quantum algorithms. This paper presents advancements achieved by utilizing temperature monitoring to enhance the S/N and successfully implement quantum algorithms. We also show a possible syllabus for conducting quantum computing experiments for undergraduate students.本誌: 電気学会論文誌A（基礎・材料・共通部門誌） Vol.144 No.7 （2024）本誌掲載ページ: 252-257 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejfms/144/7/144_252/_article/-char/ja/
