论文摘要
基于量子点（QD）的Majorana零模式（MZM）的测量方案具有当前感兴趣，因为它们为拓扑量子计算提供了可扩展的平台。在耦合的QUB-QD设置中，我们计算了QD电荷的依赖性及其差异电容对2 mzm和4-MZM测量值的实验可调参数的依赖性。我们通过考虑$ 1/f $噪声的噪声，隧道振幅或相位来量化噪声对测量可见性的影响。我们发现，通常可取或接近呼声的测量值是可取的，并使用保守的噪声估计值预测，噪声耦合与QDS并不是对拓扑量子的高保真测量的限制。
Measurement schemes of Majorana zero modes (MZMs) based on quantum dots (QDs) are of current interest as they provide a scalable platform for topological quantum computation. In a coupled qubit-QD setup we calculate the dependence of the charge of the QD and its differential capacitance on experimentally tunable parameters for both 2-MZM and 4-MZM measurements. We quantify the effect of noise on the measurement visibility by considering $1/f$ noise in detuning, tunneling amplitudes or phase. We find that on- or close-to-resonance measurements are generally preferable and predict, using conservative noise estimates, that noise coupling to the QDs is not a limitation to high-fidelity measurements of topological qubits.
