摘要:

我们提出了一个可扩展的固态伊辛自旋量子计算机的通用量子门的实现协议的任意叠加的量子态。自旋链由1/2相同的自旋组成,相邻自旋之间存在伊辛相互作用。自旋的选择性激发由外部磁场的梯度提供。协议是由矩形射频脉冲构建的。相位和不必要的过渡所造成的概率误差被最小化,并计算数值。

英文摘要:

We present protocols for implementation of universal quantum gates on an arbitrary superposition of quantum states in a scalable solid-state Ising spin quantum computer. The spin chain is composed of identical spins 1/2 with the Ising interaction between the neighboring spins. The selective excitations of the spins are provided by the gradient of the external magnetic field. The protocols are built of rectangular radio-frequency pulses. The phase and probability errors caused by unwanted transitions are minimized and computed numerically.
