This abstract first appeared for US patent application 18483821 titled 'Superconducting Quantum Chip
Simplified Explanation
The abstract describes a superconducting quantum chip that includes a coupler and a controller. The coupler is designed to connect two superconducting bit circuits and has a frequency response curve with at least one phase inversion point. The controller is responsible for adjusting the frequency response curve of the coupler to ensure an odd number of phase inversion points between the bit frequencies of the two circuits. Additionally, the controller adjusts the frequency of the phase inversion point to achieve a zero interaction of cross-resonance effect between the two circuits.

Original Abstract Submitted
A superconducting quantum chip includes a coupler and a controller. The coupler is configured to couple a first superconducting bit circuit and a second superconducting bit circuit. A frequency response curve of the coupler includes at least one phase inversion point, and the phase inversion point includes a resonance point or a pole of the frequency response curve. The controller is configured to adjust the frequency response curve of the coupler, so that an odd quantity of phase inversion points is included between a bit frequency of the first superconducting bit circuit and a bit frequency of the second superconducting bit circuit. The controller further adjusts a frequency of the phase inversion point, so that an equivalent interaction of cross-resonance effect of the first superconducting bit circuit and the second superconducting bit circuit is zero.
