来自交换相互作用和全局磁场的单自旋量子逻辑门

One-spin quantum logic gates from exchange interactions and a global magnetic field

Lian-Ao Wu, Daniel A. Lidar, Mark Friesen

摘要:

人们普遍认为,基于自旋的量子计算机中的单量子比特门存在严重的技术困难。我们表明,一个量子位门实际上可以产生使用只有适度的和目前可行的技术要求。我们的解决方案只使用全球磁场和可控海森堡交换相互作用,从而规避了单自旋寻址的需要。

英文摘要:

It has been widely assumed that one-qubit gates in spin-based quantum computers suffer from severe technical difficulties. We show that one-qubit gates can in fact be generated using only modest and presently feasible technological requirements. Our solution uses only global magnetic fields and controllable Heisenberg exchange interactions, thus circumventing the need for single-spin addressing.
