With so much happening in the technology domain, it becomes very difficult to keep up with it. With the introduction of blockchain, chatbots, LLMs and other complex topics, we are no longer at the privilege of getting to know the field. We are generally caught up in the race of being the first one to master the topic or build something out of it. However, this makes us keep on switching from one topic to another and we end up being a master of none. 要追求一个领域,它变得至关重要的是与它试图理解的主题或现象共鸣。毕竟,这是一个长期的承诺. 说到这一点,在研究其应用之前,了解技术的起源变得至关重要。 它有助于你与原因联系并引导你走上更大的道路。 这不仅有助于你回答问题 - 技术的起源,基本的性质,我们试图解决什么或领域的演变看起来是什么,但它会使你更接近技术的本质。 量子计算是一个复杂的主题,直接潜入应用程序会使它变得更加复杂,但是,看它的起源会让你更接近原因。 ” comes into picture. Its an example of what made physicists so interested into this topic and how mesmerising it could be to visualise what the possibilities are and we do not know to what extend the unknowns exist in the universe that are not yet pinned by out laws or axioms or mathematics. Double Slit Experiment History of the Double Slit Experiment The debate over whether light is a particle or wave goes back centuries. Double Slit experiment was first conducted by Thomas Young in 1801 at The Royal Institute. Yes, it goes back ~40 years. The basic idea was based on the fact that if two sounds interact with each other they create a beat and similar can be true for optical equivalents as well. While pondering over Newton’s corpuscular theory, he also observed that the air and water interaction sometimes leads to light reflection and at some places its refracted. For answering a few questions like this, he came up with the double slit experiment. Let’s look at what the experiment is all about. I will be taking you one by one and help understand the logic of it and why it matters or an essential discovery for quantum mechanics. 双重分割实验 双切片实验背后的基本想法是,电子被传递到有两个切片的板子上(如故事的覆盖中所描述的那样),并在屏幕上观察相应的结果,这是板子。 Round 1 (Balls) 1 slit 一个非常简单的描述,首先我们从一个片段投掷小球开始,这就是输出应该是什么样子: Now, this looks alright that some of the balls will bounce of the screen and the ones that pass will form a structure like that on the wall. 2 Slits 同样,这里现在有两个裂缝,墙上会有两条线。 (light) Round 2 让我们用单色光重复实验,看看当它的两个裂缝时模式会是什么样子。 The result shows a wave length of light where the light from two slits interacts and at someplace it cancels it effect (dark patches on wall) and other it combines thereby enhancing the light and you should be able to see that on the screen itself. However, the quantum physics has a letdown from there however lets look at how electrons behave and this will be a step towards understanding basics of quantum physics and how the qubits come into picture. Round 3 (electrons) It was quite understandable how light behaves in this manner however, while doing this experiment with electron says this: hypothesis: It behaves like small balls and will leave two lines similar to slit on the wall Above results are totally astounding, instead of behaving like small balls and creating two lines on the wall it depicts a light like behaviour. but that doesn’t seem logical. If the electron is thrown though the slits either they go though slit 1 or slit 2, it should not be behaving like that. Adding an observer To make sense out of this, it was decided that the electrons will be observed to check how this pattern is being created what electron goes through what slit and check if how they refract. Therefore, an observer was added need the split screen to observe this and the results were as follows: 这是另一个神秘,如果观察到电子,它们会表现得不同,这就是量子比特的概念可以与之相关的地方,观察到状态的那一刻,它们是不可逆转的,就像施罗丁格的猫实验一样,一旦打开盒子,输出就不可逆转。 结论 我不想在这里添加任何结论,我想保持你的想法的燃料. 这是一个现象,不能轻易得出结论。 然而,我希望留给你这个著名的量子力学引用: Niels Bohr If quantum mechanics has not profoundly shocked you, you have not understood it yet - 尼尔斯·博尔 If quantum mechanics has not profoundly shocked you, you have not understood it yet - Please feel free to contact if you would like to talk more about it.
