Abstract
A technique relates to a superconducting chip. Resonant units have resonant frequencies, and the resonant units are configured as superconducting resonators. Josephson junctions are in the resonant units, and one or more of the Josephson junctions have a shorted tunnel barrier.
Claims20
A method of identifying a superconducting chip comprising:
- receiving resonant frequencies associated with the superconducting chip;
- using the resonant frequencies to identify the superconducting chip based on the resonant frequencies being in two different frequency bands.
A method of causing identification of a superconducting chip comprising:
- causing the superconducting chip to provide resonant frequencies;
- and
- using the resonant frequencies to identify the superconducting chip based on the resonant frequencies being in two different frequency bands.
