查询词典 quantum state

THE war that has just erupted apparently without warning between Israel and Lebanon looks miserably familiar. The wanton spilling of blood, the shattering of lives and homes, the flight of refugees: it has all happened in much the same way and just the same places before. In 1982 an Israeli government sent tanks into the heart of Beirut to crush the "state within a state" of Yasser Arafat and his Palestine Liberation Organisation. A quarter of a century later, Israel's air force is pulverising Lebanon in order to crush the state within a state established there by Hizbullah, Lebanon's Iranian-inspired "Party of God".

我们再一次看到了充斥着鲜血、家破人亡的惨象以及战争难民的极其熟悉的荒谬场面——一个在同样的地方用同样的方式多次重复着的场面。1982年，当时的以色列政府曾派出坦克直捣贝鲁特去摧毁阿拉法特以及其领导的巴解组织设立于黎巴嫩的&国中之国&。25年之后的今天，以色列空军正在为了铲除领伊朗人意旨的&真主党&在这里设立的&国中之国&而碾碎黎巴嫩。

Any of a class of particles, such as the photon, pion, or alpha particle, that have zero or integral spin and obey statistical rules permitting any number of identical particles to occupy the same quantum state.

玻色子具有零或整数自旋状态，并且任意数目的相同粒子占据相同量子状态的统计学规则的粒子，如光子、π介子或α粒子

Then,a new result of quantum mechanics is given:considering an arbitrary manipulation of one EPR particle,which can be modeled in fullgenerality as a unitary interaction of that particle with an outside system or ancilla,ini-tially in a pure state,we shall show that such interactions can be used to prepare all andonly those states of the joint system(two particles in arbitrary entanglement and theancilla)that yield unperturbed marginal statistics for all measurements on the anotherparticle,with which the ancilla did not interact.

首先，我们介绍了量子通讯的概念是如何被引入的；其次，我们给出了一个新的量子力学结果：制备一对EPR粒子，然后把它们分开，如果我们对其中的一个粒子进行操作，那么该操作将不会改变另外一个粒子的单独测量的期望值。

We show that, for N parallel input states, an antilinear map with respect to a specific basis is essentially a classical operation. Later, We investigate the information contained in phase-conjugate pair |, and prove that there is more information about a quantum state encoded in phase-conjugate pair than in parallel pair.

在量子信息中，由于量子叠加性，人们发现在量子比特的情况下，相互正交的两量子态可以编码更多的信息，这在经典信息论中是不存在的。

In this paper, quantum theory, the use of time evolution operator obtained by the first method for the system density operator of any time, and atomic reduced density matrix, and the atomic dipole squeezing conditions, numerical study of the mixed state -type atom of the three-level with single-mode optical field coherent interaction of atomic dipole squeezing effect.

本文采用全量子理论，运用时间演化算符方法先求出所求系统任意时刻的密度算符，和原子的约化密度矩阵，以及原子偶极压缩的条件，数值计算地研究了混合态型3能级与单模相干光场相互作用时原子的偶极压缩效应。

We may characterize an atomic state by a quantum number L.

我们可以用量子数L描写一个原子的状态。

This book analyzes, from a single perspective, some of the most important applications: the critical-point theory in classical statistical mechanics, the scalar quantum field theories in two and three space-time dimensions, and Tomonaga's theory of the ground state of one-dimensional Fermi systems.

这本书分析，从一个单个的视角，一些最重要的应用：在经典统计力学方面的临界点理论，标量量领域理论在2 和3 空间时间维，和Tomonaga 一维费密系统的基态的理论方面。

In the present state of scientific knowledge the importance of quantum dynamics is commonplace.
