Qubits based on semiconductor quantum dots have made huge progress in the recent years.Single spinqubits with ultra long coherence time,single charge qubits wth ultrafast operational speed,and single
Secret sharing of a quantum state,or quantum secret sharing,in which a dealer wants to share certain amount of quantum information with a few players,has wide applications in quantum information.The c
We propose and experimentally demonstrate an optimized setup to implement quantum controlled-NOT operation using polarization and orbital angular momentum qubits.This device is more adaptive to inputs

拓扑外尔半金属具有奇异的电子结构,其体态是在三维动量空间中线性色散的外尔费米子,体态费米面是三维动量空间中的不连续的点。因此,外尔半金属具有“三维graphene”特征性的电子结构。外尔费米子具有手征的自旋结构,并且只有Dirac 费米子自由度的一半,只能成对的出现或者湮灭。
采用金属有机盐沉积法(MOD)在YBCO 薄膜中引入一定量的纳米颗粒作为钉扎中心,可以有效地提高其在磁场下的钉扎性能。然而单一掺杂在高掺杂量下会导致YBCO 晶格畸变度过大,进而降低薄膜的织构和超导性能。这里我们采用与YBCO 晶格错配分别为正和负的两种纳米颗粒Ba2YNbO6(BYNO)和LaAlO3(LAO)对YBCO 薄膜进行共掺杂,通过对比单一BYNO 和LAO掺杂的复合薄膜发现,正负错配
Because of inevitable coupling with the environment,nearly all practical quantum systems are opensystems,where the evolution is not necessarily unitary.We proposed an efficient quantum algorithm forsi

Recently,the Floquet states of matter of quantum systems under periodic driving has attracted much attention,which opens a new door to artificially synthesize exotic quantum states of matter,especiall
We investigate high-fidelity super-fast quantum driving in a generalized nonlinear two-level system with both interparticle interaction and nonlinear energy sweep.We find that super-fast quantum dynam
Here we demonstrate a protocol which suppresses the low-frequency dephasing by qubit motion,i.e.,transfer of the logical qubit of information in a system of n ≥ 2 physical qubits1.The basic mechanism
We utilize quantum superposition principle to establish the upper and lower bounds on the stronger uncertainty relation [Phys.Rev.Lett.113,260401(2014)],i.e.,the "weighted-like" sum of the variances o
