The Quantum Computing for Computer Scientists video by Microsoft Research ( [this video] ) really hammered it home for me. It goes slowly and the presenter, in his own words "shuts up and does the math".

[this video] This video is the simplest explanation that I have found for Quantum Computing which doesn't do the whole pop-sciency "is both zero and one at the same time" nonsense.

Here is a video of a researcher at Microsoft Quantum lecturing on this: [this video] "Quantum Computing for Computer Scientists.". However, even with understanding how a Quantum Computer works at its most basic level I still have difficulty understanding the more useful Quantum Algorithms: [LINK] [LINK]

I’ve begun to put together useful resources for learning more here: [LINK] I’d like to really flesh out that page; I’ve now come across so many folks that are amazing at explaining this stuff... It’s just a time crunch to juggle all this as you might imagine ;) These two videos in particular helped me get started: 1. What is a physical quantum computer? [LINK] 2. How might one compute using it? [this video]

Learning Quantum Computing based on skill level (math is the biggest friction point, suggested pdf should save you lots of time) (Recc is personal recommendations, Hi-Recc is look at ASAP) # QC Main Ideas - Rotate, Compute, Rotate - Think in Amplitude Interference # Beginner: -(Hi-Recc) Quantum Computing Primer (1.5hr) : [this video] -(Hi-Recc) Math Primer for Quantum Computing (easiest intro/primer I found on the topic; Highly Recommend ) : [LINK] -- understand Bra Ket notation [<Bra|Ket>] (Ket as Column vector, Bra (Row vector) as Complex Conjugate of Ket (denoted as dagger) ) -- understand Kronecker product ( for multi-qubit systems) - Quantum Computing for Computer Scientists book - [LINK] -

If anyone is interested I've also created a short 1.5 hour lecture on quantum computing aimed specifically at software engineers & computer scientists, which has proven popular: [this video] I'd love to answer any questions people have. In quantum computation, state behaves like a vector and logic gates behave like matrices that multiply the vector to get a new state value. It doesn't get too much more complicated than that.

Here is a long-ish video that explains quantum computers without using pop-science hand-wavy terminology [this video]

There is absolutely no way to understand quantum mechanics without learning the math. All metaphors are faulty and will lead you to incorrect conclusions. Fortunately the advent of quantum computing has made the math quite easy - it's just linear algebra of the type one would pick up within the first week of an undergraduate course. I made a video aimed at computer scientists which you might find useful: [this video]
