1610年代,"总数,数量",源自拉丁语 quantum(复数 quanta)"与...一样多,有多少?有多远?有多大程度?",中性单数对应的代词形容词 quantus "一样多"(见 quantity)。
这个词在物理学中由马克斯·普朗克于1900年直接从拉丁语引入,意指"能够存在的最小数量"; 并在爱因斯坦于1905年加强了这个概念。Quantum theory 出现于1912年; quantum mechanics 出现于1922年。术语 quantum jump "从一个稳定状态到另一个稳定状态的突变"记录于1954年; quantum leap "突然的巨大进展"(1963年)常常是比喻性的。
〔复guanta〕量子:为量子学说中的能量单位,写作hυ,其中h为Planck常数,为6.55×10-27,υ为与能量相关的振动频率。见theory项下的quantum theory

the smallest amount of many forms of energy (as light)
quantum2 of 2adjective
of or relating to the principles of quantum theory
quantum physics
quantumnoun
one of the very small increments or parcels into which many forms of energy are subdivided
a molecule of rhodopsin in the human eye can cause a response to a single quantum of light

1 However, the methods that I and other people were using in 1974 were not able to answer questions such as whether singularities would occur in quantum gravity.
2 To be human is to be quantum.

3 In the last twenty years , quantum field theory and string theory have incurred.
量子场论的建立及概念的引入过程,是现象被思维内化的过程.
4 Their conclusion was that anything one could know about an event taking place at a quantum scale was limited to what one could observe—and this knowledge depended on the means of observation.
5 A zero in quantum mechanics means that the entire universe—including the vacuum—is filled with an infinite amount of energy: the zero-point energy.
6 The uncertainty principle of quantum mechanics implies that certain pairs of quantities, such as the position and velocity of a particle, cannot both be predicted with complete accuracy.
7 In particular, no two electrons of the same quantum state can be forced into the same spot.
8 However, this can be misleading, because quantum mechanics tells us that the particles do not have any well-defined axis.
9 The fundamental rules of quantum mechanics are very broad.
量子力学的基本法则是广泛的.

13 The alternative histories hypothesis sounds rather like Richard Feynman’s way of expressing quantum theory as a sum over histories, which was described in Chapters 4 and 8.
14 Now, you recall in Bohr the quantum condition.
现在,回忆一下波尔量子理论。
15 Einstein’s earlier pathbreaking work on the photoelectric effect suggested strongly that light was composed of a stream of “light quanta,” or particles.
16 They vibrate only with certain acceptable energies, called quanta.
17 This discovery marks a quantum leap forward in the fight against cancer.
这一发现标志着治疗癌症的一大突破。
18 Thus all the complicated structures that we see in the universe might be explained by the no boundary condition for the universe together with the uncertainty principle of quantum mechanics.
19 The development in quantum optics and in quantum information is summarized in the paper at first.
