摘要:

在纳米尺度的核磁共振半导体器件中,研究了I=3/2的四个核自旋态的任意两个能级之间的相干振荡。利用该器件,我们讨论了I=3/2系统中两个虚拟量子比特的量子逻辑运算,并提出了一种基于纵向磁化测量的量子态层析方案$M_z$ .

英文摘要:

Coherent oscillations between any two levels from four nuclear spin states of I=3/2 have been demonstrated in a nanometre-scale NMR semiconductor device, where nuclear spins are all-electrically controlled. Using this device, we discuss quantum logic operations on two fictitious qubits of the I=3/2 system, and propose a quantum state tomography scheme based on the measurement of longitudinal magnetization, $M_z$.
