Through the non - locality of the quantum entanglement , teleportation schemes of arbitrary two - particle and three - particle states are proposed 通过量子纠缠的非局域性，提出了实现任意二粒子和三粒子量子态的隐形传送的方案。
Quantum measurement can ’ t get all information of the quantum state , so it needs quantum state tomography to reconstruct the output quantum state 量子测量不能获得量子态的完整信息,因此需要采用量子状态层析对量子态进行重构。
And in quantum state tomography , different measurements on the same quantum state have interactions . so it is necessary to do optimality analysis 由于对同一量子态采用的不同测量之间有着相互联系,因此需要对测量次数进行最优化分析。
In this course , original does not be sent to receiver . only quantum state of original will be sent . sender can even know nothing of this quantum state 在这个过程中，原物并未传送给接收者，它始终留在发送者处，被传送的仅是原物的量子态。
Realizing the teleportation of a quantum state , specially the teleportation of a many - qubit quantum state , is of great importance in quantum information 实现量子态的隐形传送，尤其是多比特量子态的隐形传送在量子信息领域中有非常重要的作用。
The hamiltonian of system can be expressed by the quasi - creation operator and quasi - destruction operator that connect with the two kinds of eigenstate above - mentioned 然后将系统的哈密顿量用与上述两种量子态相联系的两种准粒子产生和消灭算符表示。
In chapter iii , a scheme for probabilistic teleporting an unknown one - particle state of s - level by a group of partly pure entangled two - particle states is proposed 在第三章，我们用l个部分纠缠的二粒子态为量子通道，实现了对单粒子s能级量子态的概率传输。
The most typical protocols among them are the bb84 protocol , which is based on the principle of uncertainty and the b92 protocol , which is based on two non - orthogonal states 其中最具代表性的是基于测不准原理的bb84协议以及基于两个非正交量子态的b92协议。
Physicists know that in both types of material , the superconductivity is caused by electrons pairing up and gathering en masse in a single collective quantum state 在这两种超导体材料中，超导电性是由于电子成双成对地集结在单一的量子态所产生，这是物理学家已知的部份。
A contrast between two methods of system estimation , gives out that the differences are based on which quantum measurement can only get partial information of the quantum state 对同为系统估计方法两者进行比较,得出其差异的根本点在于量子测量不能获得量子态的完整信息。
