Research on Magnetic Computers


Most functions in the computers that we use in our daily lives are implemented with semiconductor devices. If we could replace these semiconductor devices with magnetic devices, we could build a computer that is highly resistant to radiation and that uses very little energy, requiring no power to preserve information. While such a computer may or may not be feasible, our lab was presented with the opportunity to conduct research on magnetic computers.

I believe it was in the year 2001. A former professor had just returned from a business trip overseas and informed us that they were studying the use of magnets in logical operations there. However, magnetic bodies was not this professor’s specialty, and it was apparent that he understood little of the research and could offer no further information than the two keywords “magnets” and “operations.” There were a few ideas at that time, albeit few, for using tiny magnetic bodies and magnetic wires to perform computations. However, I had drawn no connections between the two since these devices had a long way to go before being useful for calculations. At some point, it struck me that we may be able to perform computations with small magnets if we packed several of them close together. The outcome may have been different had we first studied the existing research.

  • We held 47th colloquium on 4th April We held the 47th colloquium on 4th April, which is the first colloquium in 2016.We had honor to welcome Prof. Yasushi Yagi, and gave a lecture themed "Constitution of the Datability frontier institution", which is Handai's New strategy on Research Activities. After the lecture, we had panel discussion with Prof. Yagi, Prof. Yasuo Kanematsu, the Innovation Director, Office for University-Industry Collaboration, Osaka University, Prof Eiichi Tamiya, Vice Director of Photonics Center, and Mr. Junichiro Nakayama, Unit General Manager, Advanced Technology Research Laboratories, SHARP Corporation.The questionnaire says, though he had a lack of understanding "Datability", he came to know as much about it. Another says he is expecting much toward Photonics Center's way to involve the ...
