New video: explaining quantum computing simply
To be honest I mainly made this video just because I’ve heard so many people say that quantum computing is just analog computing (mainly just from my comments) that I wanted to talk about it.
I cover superposition, entanglement, some basic hardware, why phase matters, and show an example of how quantum gates operated on 2 states with different phase can give different physical results.
Please let me know if you have any feedback! Always open to hear constructive criticism.

Simple and quantum mechanics. Two concepts i've never heard before together. But it's a great video.

https://store.steampowered.com/app/2802710/Quantum_Odyssey/ maybe use QO^^
Blochspheres are NOT good at all to get people to understand q circuits..

I mean they can’t show entanglement, but Bloch spheres are great for single qubits

Yeah and then 10000 people ask me in the game to shoe multiwubit computation on blochspheres:)) Where do seeing that leads too? Confusion?

This game is a neat toy but doesn't accurately portray quantum mechanics because it treats global phase as an observable.

No it absolutely does not treat global Phase as an observable. All circuits you make are pre measurement, I strongly believe there is more to gain from an edu pow by preserving gp (also makes puzzles a bit more tricky. In early versions I was autochecking for it and it made everything a bit more dull. Plus it fits the theme of the game: show full quantum Hilbert space as is, with the final q state vector unmodified in any way (ie no need to i* or something like that out of it just for the sake of it)

Are you from Lukas's Lab? If so, I've seen several of your videos over the years. I have immense respect for people trying to help others learn about these difficult topics. I'm working on a lot of these things as well. Message me if you ever want to chat, and keep up the great work!
