According to the China Patent Publication Announcement, Huawei’s superconducting quantum chip patent is officially announced on November 1 with number CN115271077A.
Huawei Technologies Co., Ltd. is called “Superconducting Quantum Chip”, and the patent abstract description states: [Translated]
“The embodiment of the present invention discloses a superconducting quantum chip, including a coupler and a controller; wherein the coupler is used to couple the first superconductor A bit circuit and a second superconducting bit circuit, the frequency response curve of the coupler includes at least one phase reversal point, and the phase reversal point includes a resonance point or pole of the frequency response curve; the controller is used to adjust the frequency of the coupler A response curve such that an odd number of the phase reversal points are included between the bit frequency of the first superconducting bit circuit and the bit frequency of the second superconducting bit circuit; and the frequency of the phase reversal points is further adjusted so that The equivalent interaction of the cross resonance effect of the first superconducting bit circuit and the second superconducting bit circuit is zero.”
