In quantum computation one would need quantum logic gate which can produce entanglement efficiently.

在量子计算中我们需要能够有效产生纠缠态的量子逻辑门。

Through studying the dynamical and quantum fluctuation properties of the spin waves, in analogy with the modulation of quantum noise in light and lattice waves, and lattice waves, we calculate out the average value of spin fluctuation and get the condition of achieving the magnon squeezing states.

通过研究自旋波的动力学和量子涨落的性质，类似于光波和格波的量子噪声的调制，计算出自旋涨落的平均值，从而得到了产生磁了振子压缩态的条件。

Thus we review the train of thoughts which Heisenberg founded quantum mechanics and stress the important of the matrix forms in quantum mechanics.

在回顾了Heisenberg创立矩阵力学的基本思路之后，在其后对量子力学的论述中，强调了量子力学中的矩阵形式。

The aim of this paper is to answer the query on the foundation of quantum mechanics advanced by Tao Zongying in articles,Acta Mathematica Scientia,1982,2(2):183～192 and Acta Photonica Sinica,1997,26(9):769～770.It is shown,based on the globalism concept in quantum mechanics,that Landau and Lifshitz′s momentum probability distribution function of a particle in a one dimensional infinitely deep square potential well is correct,and that Pauli and other′s distribution function is incorrect.The problem of mome...

本文回答了文献1～2对量子力学提出的疑问基于量子力学的整体性概念指出，Landau和Lifshitz给出的一维无限深方势阱中粒子的动能概率分布函数是正确的，Pauli等人给出的概率分布函数是不正确的从量子测量理论的角度讨论了一维谐振子的动量概率分布问题，并且指出势能大于本征能量的概率不为零并不表示存在负动能的概率分布区域

In the fourth one, the joint state of Bell states is used as the quantum channel toteleport a multipartite quantum state.

第四种方案以Bell基所组成的联合量子态作为量子信道，实现了多体量子态的受控隐形传态。

However this principle exhibits itself only in a multipartite quantum system, thus it is difficult to understand it in simple single particle quantum systems.

利用这一联系反过来可以帮助我们理解广义量子干涉原理，因为在量子计算机中一切计算都是普通的量子力学所允许的量子操作，因此广义量子干涉原理就是普通的量子力学体系所允许的原理，而这个原理只是在多体量子力学体系中才会表现出来。

Furthermore, the simulations of high speed modulation in nonidentical quantum wells and quantum dot laser diodes are also available in this thesis.

另外本论文也替相异双重量子井与量子点雷射二极体的高速直接调变进行纯理论模拟，探讨双重量子井与量子点中的直接调变。

Quantum NOT gate is used to realize quantum mutation to avoid premature convergence.

引言 量子计算是信息科学和量子力学相结合的新兴交叉学科。

Generally, quantum parallelism is thought to be the main character of quantum computers.

在一般文献中，量子并行被认为是量子计算的主要特征。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
