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 () includes 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 junction included in the loop circuit (), and a capacitor (), in which the loop circuit (), the third Josephson junction (), and the capacitor () are connected in a ring shape.
