Claim 0:
1. An oscillation apparatus comprising:
an oscillator comprising a resonator and a magnetic-field generating circuit, the resonator comprising a loop circuit and a capacitor, the loop circuit comprising a first superconducting line, a first Josephson junction, a second superconducting line, and a second Josephson junction connected in a ring shape, the magnetic-field generating circuit being configured to apply a magnetic field to the loop circuit, and the oscillator being configured to perform parametric oscillation;
a read-out circuit for reading out an internal state of the oscillator; and
a filter configured to restrict transmission of a signal in a predetermined frequency band, wherein
the capacitor and the loop circuit are connected in a ring shape to constitute a ring circuit in the resonator, and
the ring circuit is connected to the read-out circuit through the filter.
