Sabine Hossenfelder explains atomic energy levels and their role in quantum mechanics.
Watching these videos is all part of my plan to understand the fundamental forces behind quantum computing.
As I study the particulars of quantum computing, there are some concepts that are harder to grasp than others.
Fortunately, we live in the age of YouTube.
Here’s a greate video on quantum spin states with 3D animations.
Two Bit da Vinci ponders what recent advances in quantum computing mean for science, medicine, and humanity.
While it’s unlikely that your next laptop or cellphone will be a quantum computer, I wouldn’t rule out the idea of the iPhone Q coming out sometime in the next decade or two.
Quantum computers can solve problems in seconds that would take “ordinary” computers millennia, but their sensitivity to interference is major engineering obstacle.
Now, researchers claim they’ve created a component that drastically cuts down on error-inducing noise.
Seeker explains how graphene could make a big difference.
Geek’s Lesson provides this full nine hour source on quantum mechanics.
Quantum mechanics (QM; also known as #quantum #physics, quantum theory, the wave mechanical model, or #matrixmechanics), including quantum field theory, is a fundamental theory in physics which describes nature at the smallest scales of energy levels of atoms and subatomic particles.

Sabine Hossenfelder explains one of the most common misunderstandings about quantum mechanics — that quantum mechanics is about making things discrete or quantifiable.
This must be one of the most common misunderstandings about quantum mechanics, But is an understandable misunderstanding because the word “quantum” suggests that quantum mechanics is about small amounts of something. Indeed, if you ask Google for the meaning of quantum, it offers the definition “a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.” Problem is that just because energy is proportional to frequency does not mean it is discrete. In fact, in general it is not.
Thoughty2 explores the impact that quantum computing will have.
Sabine Hossenfelder explains the most important and omnipresent ingredients of quantum mechanics: what is the wave-function and how do you calculate with it.
Much of what makes quantum mechanics difficult is really not the mathematics. In fact, quantum mechanics is one of the easier theories of physics. The mathematics is mostly just linear algebra: vectors, matrices, linear transformations, and so on. You’ve learned most of it in school already! However, the math of quantum mechanics looks funny because physicists use a weird notation, called the bra-ket notation. I tell you how this works, what it’s good for, and how to calculate with it.
