I've recommended this here before, but David Mermin's "Quantum Computer Science: An Introduction" is also good (like this paper, it's targeted at computer scientists who have a little math knowledge and little-to-no physics background). There's a dead-tree version, but the lecture notes the book is based on are available online: http://www.lassp.cornell.edu/mermin/qcomp/CS483.html

I've been meaning to get into it but someone recommended me this series on youtube https://www.youtube.com/watch?v=X2q1PuI2RFI&list=PL1826E60FD...

Quantum Computation and Quantum Information by Nielsen and Chuang is the standard introduction to quantum computing. Besides that, you can find some old CS191 Vazirani lectures on the internet.

Here is a medium post targeted at layperson that covers a lot of same material. "Quibbling Over Qubits" https://medium.com/@_NicT_/quibbling-over-qubits-f2ca1b87f47...

This is the best explanation I've found:

r/QuantumComputing[1] is a great place if you want to learn more. We read and discuss one Quantum Computing paper a week.
