The Double Slit experiment with hacker style :-)

Wave & Particles behavior experiments with style (Hacker & DIY mode on)

Could help to understand why a “Quantum bit” (or for short a “Qubit”) could be a “more powerful” hardware support to leverage computing as it’s rely on quantum mechanic behavior – Qubit = more than one state at a time !

Today, I wish to share with you my last experiment about my beginning journey to the understanding of quantum mechanic and quantum computing domain. May be you  already known that everything in the Univers could behave as a Wave and as a Particule at the same time. And ,as far I understand, each peaces of matters in the univers could behave like that until we observe it ! Those “small particules behavior phenomena” seems to be one of the fondamental aspect of quantum mechanic (again,  as I understand it for now)

OK… but How to verify that ? here is come the “Double Slit Experiment” but, as a security guy, we will try to conduct this experiment with….style

  • and more precisely …. with a hacker and Do It Yourself  mind style.

Ready?

In fact , many of you should have heard or read that light is composed of small particule call “photons”.

 Thus, if I send a bunch of photon (whit a laser?) again a wall… you will see  a small spot on the wall. see on the right…

Nothing strange…for now…

 

But if we send this laser beam through a double slit made with a cutter on a solid paper (left on side below)…with a very  technical and expensive experimental tools with Word wide scientific precision  🙂

 

 

 

 

 

 

What would be the result on the wall after the light of the laser beam pass trough the double slit ?

Strange and non intuitive things arise here : You will see this on the wall

What’s going on with those crazy photons ? it seems that light behave as a wave !? (as we see interference pattern which , if I refer to littérature available on internet, is a fondamental behavior of a wave !

How it works?

(image of this simulation of those crazy photons behavior found on Wikipedia)

Thus, we could conclude that a laser beam (light) behave some time as a particule (the spot) and sometime as a wave (through the double slit)

Welcome in quantum word !

But believe me (or not) this could help us to designed a new type of computer : A quantum computer… and this experiments works if you send ELECTRON through a double slit instead of light

For all readers, we recommande to watch a complete scientific explanation done by Jim Al-Khalili presented at the royal institution in 2013 (Best Video I watched about this experiment)

Reference of this experiment is related to the work of a scientific, as mentioned by wikipedia as follow :

”  A simpler form of the double-slit experiment was performed by Thomas Young in 1801 (well before quantum mechanics). He believed it demonstrated that the wave theory of light was correct, and his experiment is sometimes referred to as Young’s experiment”

Note: this article was written in listening of “Coming Back to Life ” from Pink floyd… perfect match for those weird stuff 🙂
