    • A process for entangling quantum states of respective quantum systems measures electromagnetic radiation emitted from a first system and from a second system. The two systems are exposed to excitation radiation having a probability per time of producing a photon, and an interference element is coupled to receive photons from the first and second systems. The process further includes measuring a time during which the first and second systems were exposed to the excitation radiation before a photon is detected on either output channel of the interference element and applying an electromagnetic pulse that causes a relative phase shift of a portion of a quantum state of the first and second systems. Parameters of the electromagnetic pulse are selected based on measurements of the electromagnetic radiation from the first and second systems and the time measured.
    • 用于纠缠相应量子系统的量子态的过程测量从第一系统和第二系统发射的电磁辐射。 两个系统暴露于具有产生光子的时间概率的激发辐射,并且耦合干涉元件以接收来自第一和第二系统的光子。 该过程还包括测量在干扰元件的任一输出通道上检测到光子之前第一和第二系统暴露于激发辐射的时间,并且施加电磁脉冲,该电磁脉冲引起量子的一部分的相对相移 第一和第二系统的状态。 基于来自第一和第二系统的电磁辐射的测量和测量的时间来选择电磁脉冲的参数。
