Chaotic computer including spin soliton, operation method of chaotic computer, and chaotic computing method using spin soliton

A chaotic computing method using a spin soliton, the method comprising:

• setting the spin soliton to a first initial state;
• applying a first input value based on first input data and on a chaos signal to the spin soliton;
• while the spin soliton of the first initial state generates a chaotic behavior in response to the first input value and to the chaos signal, measuring a first output value and generating first output data based on the first output value;
• setting the spin soliton to a second initial state;
• applying the first input value and the chaos signal to the spin soliton;
• and
• while the spin soliton of the second initial state generates a chaotic behavior in response to the first input value and the chaos signal, measuring a second output value and generating second output data based on the second output value,
• wherein each of the first initial state and the second initial state of the spin soliton independently indicates at least one of a location of a central spin of the spin soliton or a shape of the spin soliton.

A chaotic computer comprising:

• a chaotic logic device including a magnetic thin film configured to have a spin soliton formed therein;
• and
• a processor configured to execute machine-readable instructions that, when executed by the processor, cause the chaotic computer to generate an initial value to be applied to the chaotic logic device based on an initial state corresponding to a target logical operation,
• to generate an input value to be applied to the chaotic logic device based on input data,
• to generate a chaos signal such that the chaotic logic device operates in a chaotic mode, and
• to measure an output value from the chaotic logic device and to generate output data based on the output value while the chaotic logic device operates in the chaotic mode in response to the input value and the chaos signal,
• wherein the output data corresponds to a result of the target logical operation for the input data.
