Thank CTOnews.com netizens Mutian, vegetables for the clues delivery! According to the China Patent announcement of the State intellectual property Office (application no.: CN115271077A), the Superconducting Quantum Chip of Huawei Technology Co., Ltd. was released on November 1, CTOnews.com11 reported on March 2.

The patent applied for by Huawei Technology Co., Ltd. is called "superconducting quantum chip". The patent summary description states that: the embodiment of the invention discloses a superconducting quantum chip, including a coupler and a controller; wherein the coupler is used for coupling the first superconducting bit circuit and the second superconducting bit circuit, and the frequency response curve of the coupler includes at least one phase reversal point, which includes a resonance point or pole of the frequency response curve. The controller is used for adjusting the frequency response curve of the coupler so that an odd number of 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 point 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.

CTOnews.com understands that embodiments of the invention reduce crosstalk between qubits.
