    • Embodiments of the present invention are directed toward the field of spintronics, and in particular, systems and devices capable of performing spin coherent quantum logic operations. The inventive spin valve comprises two ferromagnetic electrode layers, and a non-magnetic conducting layer positioned therebetween. An external magnetic field B0 is applied in the Z direction, such that the two electrode layers are each magnetized in a direction substantially parallel to the external magnetic field. Rather than attempting to change the magnetization of one of the ferromagnetic layers, as is the case in prior art technologies, it is the direction of the electron spin that is manipulated in the present embodiments while the electron is traveling through the middle, nonmagnetic layer. One of the ferromagnetic electrodes may be the tip of a scanning tunneling microscope (STM). This configuration may further comprise a bias voltage source connected between the STM tip and the other ferromagnetic electrode, such that a spin polarized tunneling current is conducted between the two.
    • 本发明的实施例涉及自旋电子学领域,特别是能够执行自相关量子逻辑运算的系统和装置。 本发明的自旋阀包括两个铁磁电极层和位于它们之间的非磁性导电层。 在Z方向上施加外部磁场“B”,使得两个电极层在大致平行于外部磁场的方向上被磁化。 与现有技术中的情况一样,不是试图改变铁磁层之一的磁化,而是在电子行进通过中间非磁性层时在本实施例中操纵的电子自旋的方向。 铁磁电极之一可以是扫描隧道显微镜(STM)的尖端。 该配置还可以包括连接在STM尖端和另一个铁磁电极之间的偏置电压源,使得在两者之间进行自旋极化隧穿电流。
