Microsoft created elusive particles to build the world's most accurate quantum computer.
Can particles really exist in all possible places at once?
It's exists as a cloud of particles.而当我们观察一个粒子的时候,非常奇怪的事情发生了。
When the particle is observed, something strange appears to happen.
Light from the star seemed to be passing through a haze of particles.Combinations with other parts of speech
在量子力学中,叠加意味着一个粒子可以同时以多种状态存在,就像薛定谔的猫一样。
In quantum mechanics, superposition means that a particle can exist in multiple states at the same time, just like Schrödinger's cat.只是观察一个粒子的路径--即使观察行为没有干扰粒子的运动--结果就发生了改变。
The simple fact of observing the way the particles- even if this observation should not interfere with the movement of particles changes the result.量子力学说,关于一个粒子的信息--它的质量、动量、温度等等--永远不会被摧毁。
Quantum mechanics says that information about a particle- its mass, momentum, temperature and so on- can never be destroyed.这样一个粒子体系的行为正和产生驻波的一个小乐器一样。
Such a system of particles behaves like a small acoustical instrument in which standing waves are produced.假设我们有一个粒子群,并希望对每个粒子抽样一个数,使结果值符合Rayleigh分布。
Suppose that we have a particle population and want to sample one number per particle so that the resulting values follow the Rayleigh distribution.我们给每一个粒子一个随机的x和y位置,将它的z位置设置为zpos。
We give each particle a random x and y position, and set its z position to the loop iterator zpos.我们可以很好地测量出一个粒子的位置,但是它没有波长,所以我们不知道它的动量。
We can know a particles position very well, but it doesn't have a wavelength, so we don't know its momentum.爱因斯坦经过说“光自身便是一个粒子”解说了光电效应,他后来获得了诺贝尔物理学奖。
Einstein explained the photoelectric effect by saying that“light itself is a particle,” for which he would later receive the Nobel Prize in Physics.科学家们展示,粒子对中的一个粒子,能够预测与其相距遥远的“孪生粒子”在未来会做什么。
Scientists showed that pairs of particles could anticipate what their distant twins would do in the future.每个基本粒子都由一根弦组成--就是说,一个粒子就是一根弦--而所有的弦都是绝对相同的。
Each elementary particle is composed of a single string- that is, each particle is a single string- and all strings are absolutely identical.主页gt;gt;连gt;gt;问工程师gt;gt;如何做一个粒子加速器工作,以及为什么需要这么大的结构??
Homegt;gt;Connectgt;gt;Ask an Engineergt;gt;How does a particle accelerator work, and why are such large structures necessary?一个粒子在被观察之前不能被认为有任何确定的存在--如,持续时间和在空间的位置。
A particle cannot be thought of as having any definite existence- either duration or a position in space- until we observe it.简要地说,德布罗意觉得电子不仅是一个粒子,也是一种波,它还有“波长”。
In brief,DeBroglie thinks that electron is not only a particle, but also a wave, it also has a“wavelength”.当你观察一个粒子穿过小孔时,它像个子弹,穿过其中的一个孔。
When you watch a particle go through the holes, it behaves like a bullet, passing through one hole or the other.爱是上帝,意味着我死去,一个粒子的爱,应当回到一般,永恒的来源。
Love is God, and to die means that I, a particle of love, shall return to the general and eternal source.”.沙阿,阿沛,“为一个粒子轨道克尔黑洞至20牛顿后顺序重力波通量:一个数值的方法,”物理层。
Shah, Abhay,“Gravitational-wave flux for a particle orbiting a Kerr black hole to 20th post-Newtonian order: a numerical approach,” Phys.然而,直到最近,还需要一个粒子加速器将电子“弹射”到色散关系的线性部分。
Until recently, though, it took a particle accelerator to“catapult” an electron into the linear section of the dispersion relation.即使你把纠缠粒子分开数十亿英里,改变一个粒子也会引起另一个粒子的变化。
Even if you separate entangled particles by billions of miles, changing one particle will induce a change in the other.一旦你进行观察,波函数”崩溃,”离开一个粒子在一个明确的状态。
(Once you make an observation, the wave function“collapses,” leaving a particle in a definite state.).当我们绝对以这种方式完成家具的每一个粒子,然后我们检查了房子本身。
And when we had absolutely completed every particle of the furniture in this way, then we examined the house itself.它不做他们一点好,--一个粒子,他们变得越来越差。
And it don't do'em a bit good,-not a particle,- they get worse and worse.但在黑洞视界附近存在特殊情况:其中一个粒子可能落入黑洞,而另一个侥幸逃脱。
Near a black hole horizon, however,things are different: one of the particles can fall into the black hole, while the other stays outside.
We cannot know the exact position and speed of a particle at the same time.只是观察一个粒子的路径--即使观察行为没有干扰粒子的运动--结果就发生了改变。
Simply by observing a particle's path- even if that observation should not disturb the particle's motion- we change the outcome.
