The identification of spacial noise correlation is of critical importance in developing error-corrected quantum devices,but it has barely been studied so *** this work,we utilize an effective method called qubit motion,to efficiently determine the noise correlations between any pair of qubits in a 7-qubit superconducting quantum *** noise correlations between the same pairs of qubits are also investigated when the qubits are at distinct operating ***’s more,in this multi-qubit system with the presence of noise correlations,we demonstrate the enhancing effect of qubit motion on the coherence of logic qubits,and we propose a motion-CPMG operation sequence to more efficiently protect the logic state from decoherence,which is experimentally demonstrated to extend the coherence time of logic qubits by nearly one order of magnitude.

采用基于焓法的Solidification/Melting模型研究了固相区石蜡受热融化的相变特性以及液相区石蜡的流动特性。结果表明:在相同边界条件下方腔内石蜡融化出现多解现象,融化速率也不同;在液相区,底部石蜡液相区自然对流的流动状态受Ra影响;当Ra=3.5×10^(4)时相空间轨迹表现为一定点;当Ra=2.19×10^(5)时相空间轨迹表现为极限环;当Ra=2.3×10^(6)时相空间轨迹表现为混沌状;控制上下壁面温度恒定,通过改变模型的高度来改变Ra,可以控制液相区流场的最终状态。

运用有限容积法,在不同无量纲管间距下对空气横掠椭圆管束进行二维数值模拟,对尾迹的流动变化过程和相应的分岔现象进行了分析。结果表明:保持初始边界条件不变,在无量纲管间距为0.5~3.5时,随着雷诺数增大至相应的临界值,Hopf分岔的发生使得尾迹从稳定的对称流动进入准周期状态;管间距较小时系统还会发生音叉分岔,间隙流动的偏离加剧了流动状态的不稳定性,随着雷诺数的进一步增大,尾迹中稳定的偏离快速过渡到不稳定的偏离,系统从准周期状态进入混沌状态;无量纲管间距较大时,同相和反相流动的出现使得尾迹扰动更规律,间隙流动会随着后方尾迹发生摆动,系统不再发生音叉分岔,系统最终进入准周期状态。
