Abstract: A control method is proposed that controls inter-component phase difference solitons by using splitting or fusion caused by the interaction between inter-component phase difference solitons themselves, without the need for application of external energy.

Abstract: The length portion of part of a multiband superconductor line 10 is used as a closed circuit line part Rc that constitutes part of a closed circuit allowing passage of an electric current Io generated by an electric current source 12. Meantime, the line part extending and continuing into the closed circuit line part Rc is used as an open circuit line part Ro adapted to serve as an open circuit regarding the electric current source 12. By keeping the multiband superconductor line 10 under a temperature environment falling short of the critical soliton temperature and injecting a nonequilibrium electric current Io from the electric current source 12 into the closed circuit line part of the multiband superconductor line, it is rendered possible to induce generation of an interband phase different soliton So. The generated interband phase difference soliton So is forwarded as separated from the electric current Io to the open circuit line part Ro and is made to run therein.

Abstract: A recording method that records information in soliton units, a computing method that performs a computation, an information transmission method, an energy storage method, a magnetic flux measurement method and a quantum bit constitution method utilize the properties of phase solitons manifested between superconducting order parameters present in multiple bands in a superconductor having a multiple bands. The phase difference soliton is maintained, so information can be stored in the form of phase differences. Moreover, ??soliton phase slip will also be present when the same energy is carried in the reverse direction, so the soliton itself can have a + or ? sign. The soliton enables storage of energy not accompanied by magnetic flux. Also, with soliton units, magnetic flux can be measured with greater precision by discriminating external magnetic flux. Moreover, using solitons and anti-solitons makes it possible to constitute quantum bits required in quantum measurements.
