位于美国加州SantaBarbara的量子计算技术研究所的Awschalom博士及其同事们宣称他们可以在半导体内一个有限的区间里 ,用电子自旋的取向来控制原子核自旋的取向 .这项技术要求激光、固体物理和核磁共振等学科的配合 .Awschalom博士的研究组首先利用金属印刷工艺在半导体内产生 Dr. Awschalom and colleagues at the Institute of Quantum Computing at Santa Barbara, California, USA, claim they can control the spin orientation of the nucleus in terms of electron spin orientation over a finite interval within the semiconductor, a technique that requires a laser, a solid Physics and nuclear magnetic resonance and other disciplines .Awschalom’s research team first use of metal printing process in the semiconductor generated
