You need to understand some mathematics before learning quantum computing. I can recommend 'Essential Mathematics from Quantum Computing' by Leonard S. Woody III, which is short, easy to understand and covers the basics. If you want to go more in-depth into the mathematics involved, then you have 'Linear Algebra and its Applications', by Gilbert Strang, but this book is exclusively about linear algebra, the mathematics that you use with quantum computing, not about quantum computing itself. There are a couple of popular books about quantum computing in a general sense that could be interesting to read to get an idea about the subject, for example Scott Aaronon's 'Quantum Computing Since Democritus' and Michael A. Nielsen and Isaac L Chuang's 'Quantum Computation an Quantum Information'. I do have the feeling, though, that these will be too deep for a general audience. Interesting and appealing, for sure, but perhaps difficult to understand for most people without a background in the matter. Some lectures can be really interesting as well, but, again, probably at a level that is not approachable wihout some degree of academic knowledge on the matter. for example, Ronald de Wolf's quantum computing lecture notes from the University of Amsterdam, John Preskill's quantum information lecture notes from the California Institute of Technology, and Scott Aaronson's introduction to quantum science lecture notes. Probably all these lectures are available online. Probably the best book to learn everything from the maths to the actual physical systems is 'Quantum Computing: From Linear Algebra to Physical Realizaitons', by Mikio Nakahara and Tetsuo Ohmi. This is a really complete book but also... a very expensive book! It's an academic book so not that approachable for the general public, but a great complement for those studying the subject as part of an academic course. If you want to learn rudiments of how to program with Quiskit, and other topics, vendors like IBM provide excellent resources to get the basic ideas without the need to go too deep. If you want to know more, I would recommend perhaps to do a Masters or something like that. It's not a simple topic, it requires actual study to learn physics, mathematics, and other aspects of the technology.
