The Deutsch-Jozsa Algorithm (Simple Version) - Animated Explanation

A short presentation on the Deutsch-Josza algorithm. A step by step animation (starts at 2:40 min) of the most simple quantum circuit implementing this algorithm is given. I hope it helps everyone who wants to start learning quantum computing!

Der Deutsch-Algorithmus wird mit deutschem Akzent erklärt. Outstanding.

Holy shit, bro. Thanks a lot for your explanation, it all makes sense for me now

It is hard to capture what you were saying :( But it is the clearest logic flow of DJ algorithm explanation I have ever seen.

I noticed a small error: when you are computing the tensor product you list the coefficients alpha and beta from qubit 1 as the coefficients for qubit 2. This might cause some confusion.

You will get way more views if write a transcript of what you're saying. No matter how many times I watch there are multiple parts I don't understand because I cannot tell what words you are trying to say. It would make your video the best, and probably the most watched, on the Deutsch algorithm. Please make more videos like this, but with a transcript. (Please look at the autogenerated transcript. That will help you understand what I mean.)

pozdrawiam fizyke techniczna, jedynych ludzi którym to sie przyda

When I try to have 😮 captions it gives in German. Anyone else have that problem?

Thank you for your video. The music makes me feel really sad though.
