SUPERCONDUCTING QUANTUM CIRCUIT APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18101700 titled 'SUPERCONDUCTING QUANTUM CIRCUIT APPARATUS

Simplified Explanation

The abstract describes a superconducting quantum circuit apparatus that includes several components: a resonator with a SQUID (Superconducting Quantum Interference Device), a magnetic field application part with a conductor, a current control part, and a parallel LC circuit with a superconducting inductor and capacitor.

  • The apparatus includes a resonator with a SQUID, which is a device with two Josephson junctions in a loop.
  • A magnetic field application part is present, which has a conductor through which a current passes, generating a magnetic flux that penetrates through the SQUID.
  • The current supplied to the magnetic field application part is controlled by a current control part.
  • The apparatus also includes a parallel LC circuit, consisting of a superconducting inductor and capacitor.
  • The inductor and capacitor of the LC circuit have one end connected in common to the magnetic field application part and the other end connected in common to a current path from the current control part.


Original Abstract Submitted

A superconducting quantum circuit apparatus includes a resonator including a SQUID including at least two Josephson junctions in a loop, a magnetic field application part that includes a conductor portion, a current passing therethrough generating a magnetic flux penetrating through the SQUID, the current supplied from a current control part, and a parallel LC circuit including an inductor and a capacitor each made of a superconducting material, the inductor and the capacitor having respective one ends connected in common to the magnetic field application part and respective other ends connected in common to a current path from the current control part.
