论文摘要
缓解串扰误差，无论是经典还是量子机械，对于在多Qubit Circuits中实现高保真纠缠的大门至关重要。对于微弱的无谐力量子盘，可以通过将量子与相反的鼻孔结合起来来抑制不需要的$ zz $互动。我们介绍了基于电容分流的磁通量和transmon之间的交叉共振相互作用和transmon之间的交叉共振相互作用，并证明了消除$ ZZ $相互作用的实验测量和两量栅极误差的理论建模。
Mitigating crosstalk errors, whether classical or quantum mechanical, is critically important for achieving high-fidelity entangling gates in multi-qubit circuits. For weakly anharmonic superconducting qubits, unwanted $ZZ$ interactions can be suppressed by combining qubits with opposite anharmonicity. We present experimental measurements and theoretical modeling of two-qubit gate error for gates based on the cross resonance interaction between a capacitively shunted flux qubit and a transmon and demonstrate the elimination of the $ZZ$ interaction.
