[Abstract] Maxwell theoretically established electromagnetism in Treatise on Electricity & Magnetism. Since this book is not read nowadays, not a few people do not know that experimental discussions are important in this book. Especially, Maxwell verified various laws with precise experiments. We believe that Maxwell should considered Physics is based on experiments. We discuss on Maxwell's experiments that proved Coulomb's inverse-square law. 今日の電磁気学を理論的に確立したと考えられるのはマクスウェルのTreatise on Electricity & Magnetismである。この本は今日ほとんど読まれることがないために、実験に関する記述も多いことは忘れられている。特に精密実験による様々な法則の検証に注意を払っているのは、マクスウェルが物理学を実験科学と考えていた証拠である。ここでは、クーロンの逆2乗則に関するマクスウェルの精密実験について考えよう。

[Abstract] Quantum operations robust against random noise and systematic errors are essential ingredients in the quantum control. We have theoretically studied such robust quantum operations against the errors, that consist of several elementary operations and are called composite quantum gates. In this article, we experimentally discuss the robustness of various composite quantum gates by using NMR (Nuclear Magnetic Resonance) that is one of the most familiar quantumly controlled systems. [概要] 量子制御には乱雑なノイズや系統的なエラーの影響を受け難い量子操作が必要である。我々は今までエラー耐性を持つ量子操作(複数の基本的な量子操作を組み合わせた複合量子ゲート)の理論的な研究を主に行ってきた。本稿では、最も身近な量子制御であるNMR(核磁気共鳴)を用いて、様々な複合量子ゲートのエラー耐性を実験的に調べる。

[Abstract] It seems that the importance of study on the boundary areas between the different fields of sciences and cultures is increasing with the time. The basic conditions to stimulate and promote such a study can be summarized into the three characteristic features in the modern age, that is, (1) overlapping and mutual interactions of individual specialized fields in sciences and technologies, (2) finding of symbolic and analogical view for the objects obtained by microscale analysis in modern science methodology, and (3) reflection on the negative phenomena such as environmental and ethical problems caused by rapid developments of science and technology. This is the introduction to future work to clarify the characteristics of boundary areas and find effective metholosical ways for understanding and anticipating of those areas.

Vermillion made from cinnabar ore was used for decorating the physical remains and the inner surfaces of burial facilities in ancient times. For this purpose, we measured the ratio of sulfur isotopes in the vermillion and compared the measurements with cinnabar ore collected from four mines in Japan and China, and to try and find the source of the vermillion used in ancient times. There are many cinnabar mines in Japan. Therefore, the aim of the present study is to measure the ratio of sulfur isotope of cinnabar ore in Japanese mines and to compare the ratio with mines in China. Sulfur isotope ratios in cinnabar ore collected in north, east and center regions in Hokkaido is about −4%, while the ratios of +4 to +9% are measured in the Hidaka and south regions of Hokkaido. While the ratio of ore from the Niu mine in Mie measured −8.9%. While, the ratio of ore collected in the Kamio and Yamato mines in Nara are −3.0 and −3.1%, respectively. The ore from Tokushima mines measured −3.6 to −4.0%, with −5.3 to −5.8% from the Ehime mines, and −2.4% from the Kochi mines. In Kyushu, the ratios are -3.5 to -6.3 from the Oita mine, +1.9 from the Nagasaki mine, and -3.6 from the Kagoshima mine. From the present study, the ratio of sulfur isotopes in the cinnabar ore collected from Hokkaido mines is dependant on the mine. In contrast, the ratio in ore collected from the Niu mine shows significantly different from the ore in other mines. Therefore, it is concluded that the vermillion made from cinnabar ore collected from Niu mine can be determined from the measurement of the sulfur isotope ratio.
