要約(英語): We are developing a user-friendly tabletop NMR (Nuclear Magnetic Resonance) quantum computer for student labs. 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.
