Quantum Physics: The Best Science Videos on Entanglement, Reality, and the Quantum World
Our guides to Quantum Mechanics and Quantum Computing cover the science behind these conversations in depth.
What Quantum Mechanics Is Really Telling Us
Start here. These two build the foundation: one corrects the myths that have grown up around the subject, the other shows the whole theory hiding inside a single atom.
What We've Gotten Wrong About Quantum Physics
Brian Greene leads a panel that takes apart the common misconceptions about quantum mechanics, from what "observation" actually means to the idea that anything is possible. It is a careful, deep corrective that more than earns its long runtime.

The Entire Quantum Universe Is Inside the Atom
Arvin Ash uses the humble atom to introduce the core ideas of quantum mechanics, why electrons sit in orbitals, why energy comes in discrete lumps, and why none of it works the way everyday objects do. The best on-ramp if the subject is new to you.

The Strangest Experiments
Quantum weirdness is not philosophy, it shows up in the lab. These two cover the experiments that even physicists find unsettling.
Boy, Was I Wrong! How the Delayed Choice Quantum Eraser Really Works
This is the experiment that seems to let a choice made now affect what happened in the past, and it has fooled a lot of smart people, including the presenter, who says so in the title. Arvin walks through why the spookiness is real while the time-travel reading is not.

Can Particles Be Quantum Entangled Across Time?
Einstein's "spooky action at a distance" usually means entanglement across space. This conversation pushes the idea further and asks whether particles can be entangled across time, and what that would even mean for cause and effect.

Many Worlds and Quantum Computers
Where quantum mechanics leads is still genuinely open. These two cover the most radical interpretation of the theory and its most practical application.
Does Quantum Mechanics Imply Multiple Universes?
The Many Worlds interpretation, taken seriously by the physicists who argue both for and against it. A clear look at why some of the sharpest minds alive think every quantum event splits reality into branches, and why others find that a step too far.

Quantum Computing: Hype vs. Reality
Cuts through the marketing to explain what quantum computers can and cannot actually do, and how far off the genuinely useful machines really are. The perfect companion to our quantum computing guide if you want the honest version.
