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.
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.
Einstein’s special theory of relativity combines space and time into one dynamic, unified entity – spacetime.
But if time is connected to space, could the universe be anything but deterministic? And does that mean that the future is predestined
PBS Space Time explores what this means.
In this episode, Seeker tackles the question that’s on everyone’s minds: what will it take to have quantum internet in our home?
Yes, Virginia, a quantum internet is in the works.
The U.S. Department of Energy recently rolled out a blueprint describing research goals and engineering barriers on the way to quantum internet.
The DOE’s latest blueprint for a quantum internet in the U.S. has four key milestones. The first is to make sure quantum information sent over current fiber optic cables is secure. Then to establish entangled networks across colleges or cities, then throughout states, and finally for the whole country.
In this video, Sabine Hossenfelder explains how public key cryptography works on the internet today, using RSA as example, what the risk is that quantum computers pose for internet security, what post-quantum cryptography is, how quantum key distribution works, and what quantum cryptography is.
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.
