Degenerate perturbation theory to quantum search
Dezheng Zhang, Xuanmin Zhu, Yuanchun Deng +3
We utilize degenerate perturbation theory to investigate continuous-time quantum search on second-order truncated simplex lattices. In this work, we show that the construction of t…

Hybrid direct state tomography by weak value
Xuanmin Zhu, Qun Wei, Lixia Liu +1
Compared with the conventional quantum state tomography (QST), the direct state tomography (DST) using weak value is easily manipulated in experiments. However, the efficiency of t…
