The Measurement Meaning of Observable Operator with the Heisenberg Uncertainty Relation 力学量算符的测量意义与海森伯不确定关系
In fact, Heisenberg ′ s uncertainty principle is a special case of entropy uncertainty relation, and entropy can be used to measure the quantum fluctuation of the quadrature components of the field. 海森伯测不准关系是熵测不准关系的一个特例,可用熵量度光场正交分量的量子涨落。
The result provides a new and effective method for quantum mechanical interpretation of the principle of complementarity, and shows the possibility of unifying the principle of complementarity and Heisenberg uncertainty relation. 2. 上述结果为互补原理的量子力学诠释提供了一种全新且有效的方法,并且有可能将互补原理和海森堡不确定性关系统一起来。
As the focus of research, Quantum key distribution ( QKD), which uses Heisenberg uncertainty relation and quantum no-cloning principle, not only ensures the absolute security of communication between sender and receiver, but makes the ability of detecting eavesdropper possible. 而作为研究重点的量子密钥分配利用了海森堡(Heisenberg)测不准原理和量子不可克隆定律能无条件安全地在通信双方之间实现共享密钥,并能检测到通信过程中的窃听行为。
On the other hand, Heisenberg uncertainty relation reveals that non-commuting observables can not been sharply measured simultaneously. 另一方面,海森堡不确定性关系指出不对易的可观测量不能同时精确测量。
Since quantum no-cloning and the Heisenberg uncertainty relation ensure the absolute security and the ability of detecting eavesdropper, quantum cryptography has become the most attractive frontiers in recent years. 由于量子不可克隆定理和海森堡测不准原理保证了量子密码的无条件安全性和对监听的可检测性,量子密码已经成为最具吸引力的前沿领域。
Meantime, the physical mechanism inducing the principle of complementarity is still under debate, whose focus is whether the principle of complementarity or Heisenberg uncertainty relation is more fundamental rule. 同时,互补原理的物理机制仍在争论之中,争论的焦点集中在互补原理与海森堡不确定性关系到底哪个是更基本的原理。
But for the limitation of the Heisenberg uncertainty relation, the picture of quantum phase-space is not only one. 但是由于Heisenberg的测不准关系的限制,量子力学相空间图像不是唯一的。
