Abstract
A resonator, an oscillator, and a quantum computer in which both moderate nonlinearity and a low loss are achieved, and the area occupied by the circuit can be reduced are provided. A resonator (100) includes at least one loop circuit (110) in which a first superconducting line (101), a first Josephson junction (103), a second superconducting line (102), and a second Josephson junction (104) are connected in a ring shape, at least one third Josephson junction (130) provided separately from the Josephson junction included in the loop circuit (110), and a capacitor (120), in which the loop circuit (110), the third Josephson junction (130), and the capacitor (120) are connected in a ring shape.
Claims7
A resonator comprising:
- at least one loop circuit in which a first superconducting line, a first Josephson junction, a second superconducting line, and a second Josephson junction are connected in a ring shape;
- at least one third Josephson junction provided separately from the Josephson junctions included in the loop circuit;
- and
- a capacitor, wherein
- the loop circuit, the third Josephson junction, and the capacitor are connected in a ring shape,
- the third Josephson junction is connected to the loop circuit at a certain connection point,
- and only the third Josephson junction, the first Josephson junction, and the second Josephson junction are directly connected to the connection point.
