Electronic circuit and calculator

An electronic circuit, comprising:

• a band-pass filter including a plurality of filter resonators, two adjacent filter resonators included in the plurality of filter resonators being mutually couplable, at least a portion of the plurality of filter resonators being arranged in a ring configuration;
• and
• a plurality of first circuits, each of the plurality of first circuits including a first qubit and a first readout resonator, the first readout resonator being couplable with the first qubit,
• one of the plurality of filter resonators being couplable with the first readout resonator of one of the plurality of first circuits.
