Zusammenfassung:PROBLEM TO BE SOLVED: To efficiently create a quantum entanglement state by two quantum bits arbitrarily selected from among a plurality of quantum bits. SOLUTION: In creating a quantum entanglement state between a quantum bit Q1and a quantum bit Q4, first of all, the resonant frequency ωresof a variable resonator vres is added to a sum frequency ωQ1+ωQ4or a difference frequency ¾ωQ1-ωQ4¾ of the resonant frequencies ωQ1and ωQ4of the quantum bits Q1and Q4. By irradiating the quantum bits Q1and Q4with a microwave pulse having the sum frequency ωQ1+ωQ4or the difference frequency ¾ωQ1-ωQ4¾, the quantum entanglement state of the quantum bits Q1and Q4can be created.
