Entanglement, in quantum mechanics, describes situations where different quantum systems become to tightly intertwined that each loses their own identity. The famous physicist Erwin Schroedinger remarked in 1935 that entanglement is "... the characteristic trait of quantum mechanics, the one that enforces its entire departure from classical lines of thought". The rapidly growing field of quantum information science is based on the realization that entanglement is not only the characteristic trait of quantum mechanics, but can be harnessed for truly disruptive new technologies in communication and computation.

在量子力学中，纠缠描述了不同的量子系统变得紧密交织，以至于每个系统都失去了自己的身份的情况。著名的物理学家Erwin Schroedinger在1935年评论说，纠缠是“……量子力学的特征，它迫使它完全背离经典的思想路线”。快速发展的量子信息科学领域是基于这样一种认识，即纠缠不仅是量子力学的特征，而且可以被用于通信和计算中真正具有颠覆性的新技术。
