Anyon-Quasiparticle-Qubit-Electron.
An anyon is a unique type of quasiparticle that exists exclusively in two-dimensional (2D) systems, possessing physical properties that fall strictly between those of fermions and bosons. First proposed in the 1970s and named by Nobel laureate Frank Wilczek, anyons are central to modern quantum physics and the development of topological quantum computers. /Wikipedia/
Book: "Why nobody understands quantum physics"
" ... under specific conditions, particles or electrons split into quasiparticles. It turns out that even those fundamental, seemingly inseparable particles are capable of family expansion .... These new parts-of-particles are neither fermions nor bosons. Frank Wilczek called them anyons (from the word 'anyone'). Also these anyons can be far apart, they always remain mysteriously linked by an invisible, highly elastic thread". /Page 291, by Frank Verstraete and Celine Broeckaert/
“But what practical use can we make of these anyons? … Designing a computer that operates on anyons and their permutations, could, in principle, overcome this obstacle, since the superpositions would then be protected by the intrinsic topological properties of the anyons.” /Page 292/
So how is all this even possible? …. Alexei Kitaev: the principle of quantum error correction is equivalent to the existence of anyons (those ‘quasiparticles’ from the quantum Hall effect) in highly entangled quantum systems” /Page 320/
This method involves simulating a system of (artificial) anyons using a system of ordinary qubits.” /Page 321, by Frank Verstraete and Celine Broeckaert/
So! “…under specific conditions, particles or electrons split into quasiparticles” which are “anyons” and which are “qubits” !!!
Similarly.
These specific conditions can be observed during the collapse of the Schrödinger wave function (Ψ). Born's electron (with probability |ψ|²) leaves an atom and splits into quasiparticle, which is an "anyon," and which is a "qubits".
Question: Can an electron really be a qubit of information?

Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!
it's very unfair and dangerous how you said "than computers came into being and they only spoke machine languages" etc. Don't you feel the difference between being invented by people and "came into being"???? lessons like these are very very sad for me as for scientist. you teach people to wrong vision((((

More User Perspectives
And in the end you usually don't get cake..😭🤣 4:52
@sonupaswan2296Thanks! It helps.
@Salah_-_UddinThank you!
@Albin-t5uI already love this tutorios
@PhillipSilaahow can i watch the videos in Google class
@2DAYGOALIs it heavily math based or totally different?
@squirrelz68Anyone watching in April???
@ChamaJohn-uo3icIterate. Definitions of iteration. doing or saying again; a repeated performance. repeating, repetition. the act of doing or performing again. (computer science) executing the same set of instructions a given number of times or until a specified result is obtained.

Lesson 1. What is AI.
Lesson 2. You are no longer needed, you been replaced by AI.
Hello
@TahiraBatool-t8lYou think like you're only the one who knows this stuffs I'm not a eng guy and i don't understand like how you talk like sooo fast..... And wanted you to make much more videos related to this but in like in easy words bro it's very hard for foreigners to understand how you talk and you said about the cake recipe and diff btwn cs and programming but I don't understand both of them bro listen to my comment
@Joras_EditzzzAwesome indeed!
@mikeknsahhallo
@snioperatieThank For 134 subscribe complete❤❤🎉🎉🎉
@Sohamprakashprimaryschool2004Pamela is back after 9+ years!
@user-JfoweisawsomePlease teach c++ also
@nehasingh2933Thank you Khan Academy for the teachign of both your javascript course and your Python course. I have a question though. I tried taking a CS course in my High school and the javascript was very different from what is taught in this course, I'm not sure why that is, if you could explain this I would be very grateful!
